By the end of 2018, Wu'an Municipal People's Government of Hebei Province issued a notice on the issuance of "blue sky Wu'an winning three-year action plan to defend the war", referring to the notification: By the end of 2019, the city has a depth of discharge conditions for reconstruction the coal-fired units completed in-depth treatment, meet the relevant standards. Implementation of coal-fired power management depth. Implementation of coal-fired power plants and coal-fired units emission performance management, emissions of coal-fired units to assess the performance rankings, and resolutely out of shutting down environmental protection, energy consumption, security is not up to 300,000 ten million coal-fired units.
First, the implementation of in-depth treatment of coal-fired power plant
Implementation of coal-fired power plants and coal-fired units emission performance management, emissions of coal-fired units to assess the performance rankings, and resolutely out of shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. 2018, 2019, 2020, respectively, by province and Handan given task given the amount of closed down. Heating demand complete transformation of 600,000 kilowatts grade pure condensing units, high-capacity, high-parameter units accounting for 90%
Special action to carry out deeper cuts power industry, coal-fired units in the original ultra-low emissions, based on the further optimization of operational management, improve pollution control facilities, improving removal efficiency, the implementation of colored smoke plume power plant management. Before the end of 2019, the city has deeper emission coal-fired units to complete the transformation of the conditions of the depth of management, meet the relevant standards.
Second, to carry out special treatment industrial furnaces
The development of industrial furnaces comprehensive remediation plan to carry out an intensive investigation of industrial furnaces, establish classification list management. Stringent emission standards, increase efforts to eliminate non-compliance of industrial furnaces, accelerate the elimination of small and medium gas furnace. Under the premise of resources to implement and encourage industrial furnaces use electricity, natural gas and other clean energy or heat from the surrounding power plant. Ban coal stove, substantially eliminated cogeneration heating pipe network coverage in the range of coal heated oven (furnace); out hearth diameter of 3 m or less gas furnace fuels, natural gas use conditions have temporarily , building a unified center of clean coal gas principle; prohibition blended with high-sulfur petroleum coke.
Third, the natural gas steam boiler
6T gas 70tph biomass steam boiler steam production is saturated steam it? In general yes, but it does not rule out the superheated steam. Saturated steam: soda boiling, water containing a large amount of steam; superheated steam: saturated steam heating was continued, the inside of the water into steam, a process called superheated steam is called superheated steam. Generally boiler pressure 1.6MPa, basically saturated steam; superheated steam is used to power ships, pressure 3.82MPa; special requirements but not exclusively, have seen 2.X pressure. Usually the steam temperature after the superheater is relatively high, it is necessary to cool to the desired temperature, the process temperature is called Save, Save mild surface divided spray desuperheater. Analyzing therefore saturated steam boiler or superheated steam, most direct way is to see if a desuperheater. Fuel steam boiler can be converted into coal-fired steam boilers do? Hello gas can be changed if it is horizontal (1t-4t) of fuel to be steam boiler biomass gasification boiler (transformation without changing the original structure of the boiler pressure), by applying a biomass gasification burner using pyrolysis pyrolysis and chemical oxidation, and sealed by hypoxia smolder, thermal decomposition of the biomass waste to make it work as hydrogen, carbon monoxide, methane and hydrocarbons, is a high-energy combustors for boilers or other use, saving 30-60% of fuel costs while eliminating the chimney smoke, but also greatly reduce the production of sulfur dioxide at the same time to achieve energy saving win.
Each boiler will generate 250 tons/hour of low-pressure steam for the alumina refinery; however, the design allows for conversion to high-pressure steam generation for the future addition of a steam turbine for electricity generation.Coal or biomass will be the primary and backup fuels, respectively.
