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.
