If the client needs heating, you should choose a dedicated pressure hot water boiler is heated by circulating hot water in the hot water pump recycling. Back to the radiator, i.e. a heat sink, to deliver heat to every corner; hot water only, select a particular hot water, hot water circulating through the pump, hot water tank of hot water circulating in the hot water supply; number of users need to have two choices, so they have to choose to increase the heat exchanger in the piping system, so using two atmospheric pressure hot water boiler. 2, the heating area is determined, the amount of water by the calculation cycle, the required amount of hot water, boiler design used to determine the heating area or field. Accurate and scientific calculation and design can meet the requirements, without wasting resources. 3, to determine the fuel, boiler pressure hot water boiler style, coal or natural gas hot water boiler in three common, the boiler is electricity, gas hot water boiler coal or natural gas as an energy source. When selected, you can choose your own needs or favorable conditions. As long as meet the requirements of the boiler room, the style of choice should be simple and suitable for horizontal or vertical.
Shutdown four tons of gas reasonable price brown coal hot water dhl boiler steam boiler shutdown and maintenance of fire into pressure shutdown, normal shutdown, emergency shutdown. A pressure fire fire shutdown shutdown pressure applied to temporarily stop the supply of steam, the boiler is shutdown pressure hot standby state. 1, before the pressure reduction appropriately to fire the boiler load, and according to the length of the seam thicker shutdown time, (up to 200mm) to accelerate the speed of the grate, the grate is stopped when rotated about 1.5 meters from the coal seam to the shutter. 2, stop blowers, blower suitably adjusted flap subsections, relying on a lean-burn natural ventilation is maintained. 3, the sewage, to allow the water level in the boiler water level. 4, Yang fire regularly, to prevent rotation of the furnace grate extinguish the fire bed. Young fire first before sewage water, then rinse water level gauge. II. Normal shutdown Normal shutdown for heating period ends, boiler pour fire into the buck repair or maintenance. 1, make a record before shutdown problems in operation, so that after the shutdown process. 2, the coal bucket coal memory runs out, the amount of toner to reduce the wind. 3. Stop the blower, draft fan stop and then the opened door grate ash. 4, after the steam supply is stopped out, the boiler to the boiler water to maintain a high level. 5, close the main steam valve, if the pressure rises to open the air exhaust valve suitable pressure relief. 6, stop the water supply to the boiler and economizer attention to monitoring changes in water temperature, open return pipe if necessary. 7, 4 to 6 hours after the furnace fire bed down exhausted, continued rotation of the cooling grate. Throughout the boiler throttle, the door should be kept closed. Allowed to naturally cool. 8, appropriate to open the pump, the boiler water and sewage. When the pressure drops to zero, open the air valve. 9, when the boiler water temperature is below 70 ℃, boiler water can be exhausted. Shutdown is complete. 10, less than 24 hours during shutdown. Avoid Shutdown cooling process, step-down too fast. Third, emergency shutdown emergency shutdown applies to the boiler accident, g combustion equipment damage, furnace or boiler structure collapsed wall is red-hot, a serious threat to the safe operation of the boiler when; h boiler pressure parts found serious distortion, leakage. when i found flue gas explosion or secondary combustion, boiler and seriously endanger the safety of operating personnel;; when endanger the safety of operation.. the safe operation of the boiler j endanger other unusual circumstances when. 2, the emergency shutdown procedures to immediately stop a blowing coal and reduce the wind; B rotates quickly grate, the pour slag pit coal or sand, wet ash coal burning fire to extinguish. , but not to the firebox water;. c boiler air valve, the relief valve opens quickly exhaust the steam pressure is reduced;. d after the fire goes out, stopping fan, opening the ash door and door, promote air circulation accelerated cooling; 3, emergency shutdown Notes a. when an accident and emergency shutdown due to lack of water, boiler feed water is strictly prohibited to, and shall not be such as to open the air valve or exhaust valve work on preventing boiler from sudden changes in temperature or pressure to expand accidents;. b when filled with water due to an accident and emergency shutdown, should immediately stop the water supply, reduce combustion, open the drain valve and drain, due to lower the water level, while opening the main steam pipe, the sub-cylinder and steam traps mother tube, water and prevent steam pipe with a large number of water hammer occurs. c. emergency shutdown operation to ensure the safety of the main event of an accident to calmly deal with, timely reporting, and make relevant records in the "log table boiler." d. Whether shutdown any case, we must maintain timely contact with steam departments.
February 21 this year, the Harbin Municipal People's Government issued the "blue sky Harbin win the Battle of three-year action plan to implement the program" (hereinafter referred to as the "Program"), as follows.
First, strictly control the total coal consumption
The county (city) should shoulder the main responsibility for control of the total coal consumption, according to the focus on the use of coal and clean use of principles, focusing on reduction of non-coal power, propulsion power and other clean energy alternative to coal and oil by 2020, coal accounting for the proportion of energy consumption compared to 2015 decreased by 1.5 percentage points or more.
Second, to strengthen control bulk coal
Full implementation of the "Harbin coal pollution prevention and control regulations" to strengthen quality inspection of coal, coal quality testing organizations standardized sampling, testing system, improve the sampling frequency. Promote clean and efficient coal-fired boiler, wherein an alternative embodiment the biomass must be dedicated biomass boiler, burning raw material briquettes, installation efficient dust removal equipment.
Third, steadily promote clean heating
To promote priority to the development of clean coal utilization and clean energy use, urban urban central heating. Being difficult to cover central heating, gas heating and accelerate the implementation of electrical heating and other heating decentralized cleaning implement "coal to clean energy" units should be synchronized removal of coal-fired boiler, gas boiler for an alternative to the use of low NOx combustion technologies , gas boiler efficiency can not be less than two levels. 2019, clean heating rate of more than 60%; in 2020, clean heating rate should reach 70%.
Fourth, to carry out comprehensive improvement of coal-fired boilers
To develop a comprehensive remediation plan coal-fired boilers, the implementation of cleaner alternative to coal-fired heating boilers. 2019, the urban built-up area, county (city) county towns built-up areas out of 10 tons of steam coal-fired boilers and furnaces and tea, operating the stove, grain storage and drying equipment, coal fired facilities; basic urban built-up area out of 35 tons of steam per hour coal-fired boilers; basically eliminated the urban fringe per hour 10 tons of steam coal-fired boilers; county (city) basically out of the city and county (city) financial support units (including township, village ) per hour, 10 tons of steam coal-fired boilers. By 2020, basically out of 10 tons of steam per hour urban coal-fired boilers; out of the urban built-up area per hour can not discharge standards of 35 tons of steam (or 29MW) coal-fired heating boilers. In the central heating pipe network coverage area, a ban on new or expanded scattered coal-fired boilers.
Fifth, accelerate clean energy development
Orderly development of wind power, wind power construction layout optimization, to carry out decentralized wind power development and construction in the area have developed criteria. Actively promote the construction of biomass power generation. Enhanced geothermal energy exploration, development and utilization of resources to carry out detailed investigation and evaluation of geothermal energy, geothermal energy resources in the region to find out the distribution and exploitation potential. Increase renewable energy consumptive efforts to solve the basic water abandoned, abandoned wind, abandoned light problem. By 2020, the proportion of non-fossil fuels in primary energy consumption of the city's total, compared with 2017 increased by 1 percentage point.
Electrical difference between the reasonable price brown coal hot water dhl boiler and gas boiler no real good, only for it or not. (Direct thermal electric boiler in the building standards are not allowed in the following description of an electric thermal storage boilers, there is a corresponding electric thermal storage boilers local standards) investment aspects of the common gas boiler cheaper than electric boilers at the beginning, but also the gap between the number of specific distinction, gas brand boiler size, with or without condensate recovery and technical maturity; brand electric boiler, the applicable type. Related both construction conditions, such as plumbing, gas station; selecting high and low voltage power, power distribution construction. Gas heating season in general calorific value / purity of non-compliance (even if the contract is more explicit), compared with the calorific value of the basic electrical 1: 7, the proportion of LNG to be higher, lower coal bed methane (calorific value is multiplied by the thermal efficiency of the device ). In this case, electricity savings of about 1/3 than gas, according to the grapevine, is expected this year, Liaoning low power dropped to less than 0.3 yuan (business), that electricity than the gas savings is estimated to be more than half. It covers an area of respect, if the construction of the gas gas station, then it must be a space-saving electric boiler and electric boiler is the basic module assembly, according to the actual situation; and gas boiler explosion venting port and need a certain security area. In terms of energy, electricity is no waste, waste gas, waste water, renewable energy, gas or have emissions, and fossil fuels are not renewable, although the state vigorously outsourcing, but in the long perspective, the decline in the price of more space large, but also more conducive to use, especially Valley electric. Finally, if it is 30 000 m2 of non-continuous heating conditions (such as schools, shopping mall, office, public venues, factory, warehouse, etc.), recommended to choose electric thermal storage boilers, the best choice for 10kv high voltage device, you can save some investment, and the province as well as policy. But if the area is less than 10,000 m2, the election 0.4kv low-voltage equipment is also good. Equipment and electric boilers are run automatically, without someone on duty, usually around six meters do not consider lifting frame height coefficient, the heating time can independently control these areas compared to the municipal district heating is also very advantage.
