At the end of 2018, Yantai City, Shandong Provincial People's Government Office issued the "Yantai Blue Sky win the Battle of three-year action plan implementation details," "rules" that: in principle, to new natural gas cogeneration and gas chemical projects. Details are as follows.
Continued implementation of the total coal consumption control, by 2020, the city's total coal consumption control in less than 24.19 million tons. Developed and implemented 2018-- 2020 coal consumption reduction alternatives work, the coal consumption Yajian task decomposition implemented in urban counties. Strict control of new coal project approval, approval, filing, encourage natural gas, electricity and other clean energy alternative to coal consumption. Censorship perfect substitute for coal, improve coal reduction coefficient replace coal utilization efficiency low industry. All new, revision, and expansion projects are implemented coal coal reduction alternatives, strict implementation of alternative sources and alternative proportions.
The development of special programs, out of shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance, the following priority out of 300,000 kilowatts to run at least 20 years of pure condensing unit, run over 25 years and Condensate Pumping Units still can not reach ultra-low emission standards for coal-fired units. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units.
Accelerate the phase-out of coal-fired facilities tea furnace built in the urban counties of the region, operating a stove, grain storage and drying equipment. The city's ban on new 35 steam tons / hour and coal-fired boilers. 65 steam tons / hour or more coal-fired boilers on the basis of complete transformation of the ultra-low emissions, with the transformation of the conditions to complete all energy saving. Out of coal-fired boilers heating pipe network coverage range. In the area where no cogeneration district heating conditions, a plurality of existing coal-fired boilers, and the like in accordance with the principle of building a large-capacity volume replacement coal-fired boilers.
The implementation of non-fossil energy doubling action plan, by 2020, non-fossil fuels in energy consumption should reach its goal provincial requirements, the city's wind power, solar power, biomass power, pumped storage power generation, nuclear power and other new energy and renewable energy power generation capacity reach 7.05 million kilowatts. Where the conditions of availability of resources, to encourage the development of biomass cogeneration county, increase renewable energy consumptive, improve social proportion of the total electricity consumption of renewable energy generation.
About six tons of coal fired hot water steam boiler price shutdown of a temporary shutdown: It is planned, therefore slow cooling during shutdown protection device, it should also pay attention to safety, pause furnace according to the rules in Chapter IV Fenghuo (pressure fire) get on. 2, safety shutdown: care should be completely stopped even on normal operation plan for 1 to 3 months to be a shutdown, shutdown should maintain more safety injection apparatus, after the shutdown, and other water-cooled furnace to below 70 ℃ when they let go of the gas, open manholes, hand holes, rinse the pot with water scale. 3, emergency shutdown: the boiler operation, when the case of the following circumstances, should an emergency shutdown, and notify the relevant authorities. (1) expanding the cease-fire should first see if the water table level is called to take water law. If Inception water table, water cock side, and then close the steam cock, and then turn on the water faucet open and close repeatedly called after water, still can not see the water. (2) All water supply equipment failure. (3) All water gauge, pressure gauge, safety one of all the failures. (4) a boiler or furnace wall element damage, serious threat to the safe operation of the boiler, emergency shutdown, should focus on preventing the stop of the accident and the specific steps as follows: ① first blowing off; ② the coal on the grate red raking; ③ Close induced draft fan.
Fuel oil combustion process differs from the process industry Industrial Combustion fuel oil-fired boilers for industrial oil fired boilers and industrial boilers, having a certain temperature and pressure injected into the furnace through the nozzle is atomized into fine droplets, and then absorbs heat in the furnace, vertical oil-fired boiler, surface gradually vaporized into oil, mixed with intake air in the furnace, form a combustible mixture. The combustible mixture continues endotherm temperature reached ignition ignition combustion. Fuel amount, air amount and the amount of the composite has a one to one relationship of steam, it is necessary according to the load amount of steam required to control the amount of fuel and air supply, but also by the wind furnace pressure control apparatus. Different oil-fired boiler with a different point of industrial coal-fired boilers point of industrial boiler fuel industry and industrial coal-fired boilers. PM2.5 pollution damage to the environment led some coal-fired boilers industrial boilers is facing new boiler renovation or change of situation, which makes oil-fired boiler to become the darling of the market. Oil-fired boiler with a coal-fired boiler in comparison with structurally quite different purposes, as follows: (1) injecting fuel into the boiler furnace through the burner, combustion chamber without using fire grate facilities; (2) Since the oil, gas did not produce combustion ash, it is no oil or gas boiler slag and slag outlet device; (3) injecting a gas or oil furnace materialized, if mixed with air or flame within a certain range, is easy to form an explosive gas, Thus fuel (gas) required automated combustion boiler system, comprising a flame monitoring, flame protection, explosion-proof safety; (4) Since the oil, gas calorific value is much larger than the calorific value of coal, so the thermal strength than fired furnace high multi-furnace, so relatively small and the capacity of the boiler with coal-fired boilers, compact, small footprint; combustion process (5) fuel (gas) is suspended in a boiler furnace, the furnace is provided so its before and after the arch, the furnace structure is very simple. Meter manufacturing, Supervision, Inspection and the main characteristics of biomass fuel boilers  protection devices and control systems introduced a biomass fired boiler biomass fuel boilers are in strict accordance with "Steam Boiler Safety Supervision", JB / T10094-2002 "general industrial boilers technical conditions ", JB / T1619-2002" shell boiler body manufacturing technology, "execution, ensure long-term security and stability of the boilers. Body is a shell type three return all wet back downstream pyrotechnic pipe structure, large combustion flame in the combustion chamber a slight positive pressure, stretched stretch, combustion heat load is low, less NOx emissions of harmful substances. Waveform furnace and threaded pipe structure that improves the strength, but also to meet the needs of each portion of the thermal expansion. Master butt welds are connected, and by X-ray and ultrasonic nondestructive testing, to ensure the welding quality to meet national requirements. Boiler water volume and large air space, adaptable load capacity. Design reasonable pot, with water vapor to ensure that less than 4%, to meet user requirements for higher quality steam. Using the new insulation materials, light weight, low heat loss, good insulation properties. Water level alarm stainless steel rods as electrodes, an insulating material as polytetrafluoroethylene. Inserted from above, linked to pollution easy, reliable, and long service life. Before and after the smoke box is hinged, can easily open, repair and maintenance quick and easy maintenance. Adjusting the oxygen content (optional): The system can successfully monitor the oxygen content in the flue gas, and transfer the data to the real-time control systems, intelligent analysis by a computer, the automatic adjustment device stoichiometric combustion, it is in real-time good working shape, combustion efficiency is greatly improved, which can significantly reduce fuel consumption. Biomass fuel boiler operation timing of the protection device, the operation of the control system by the timer, the system automatically enters the work or off duty. The control system may be provided multiple sets of the timing period within 24 hours. Any period of time in a group of a plurality of sets of timing of the current time period, the system enters the working state. Work within the timing period, the status screen is displayed automatically. In the period of time in commuting to work outside the state. Each group comprises a turn-on time period (hour, minutes) and a closing time (hours, minutes) may be set or modified when the three control period, divided by the setting operation and the current time. The user can set different time different temperature ranges.
6 tons gas coal fired hot water steam boiler price steam pressure adjusting a boiler operation, must frequently monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. Second, increasing boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. Third, the boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and the amount of feed water 8 to adjust. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes.
