Hefei is the blue sky to win the Battle of key areas for innovation to create an international influence is of great significance. Is determined to win the battle of the blue sky, the city combined with the actual situation, formulate a three-year action plan to win the embodiment Battle of blue sky. Details are as follows.

I. Target: 2020, sulfur dioxide, total nitrogen oxide emissions were reduced over 23.1% in 2015, more than 24.2%; PM2.5 concentration decreased more than 18% in 2015, the ratio of the number of days air quality assessment requirements up to the national , severe pollution and over several days ratio decreased by more than 25% compared with 2015; the full realization of "thirteen five" binding targets.

Second, the continued implementation of the total coal consumption control. By 2020, the city's coal accounts for a further decline in the proportion of total energy consumption; the city's total coal consumption to complete the tasks assigned by the national and provincial; new coal projects to implement the reduction of coal instead.

The development of special programs, shutting down vigorously eliminate environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement may be within the total national and provincial construction plan developed according to the control range, co-ordinate arrangements for the construction of ultra-low emission coal-fired capacity unit.

Third, the implementation of the "coal to gas" and "electricity instead of coal." Under the premise of the implementation of the gas source, protect people's livelihood, ceramic, glass, foundry industry to actively promote natural gas instead of coal gasification project, orderly implementation of coal-fired facilities from coal to gas. Combined with regional and industry characteristics can actively promote industrial production, building heating and cooling, transportation, agricultural production, the implementation of the residents living in five major areas "electricity instead of coal", focus on improving the proportion of final energy consumption of electricity accounted for. Of the new "coal to gas" projects, we should adhere to increase coal gas reduction to gas will change under the premise signed gas supply contracts, orderly implementation.

Fourth, to carry out comprehensive improvement of coal-fired boilers, coal-fired boilers to increase efforts to eliminate, consolidate the results of coal-fired boilers eliminated. Coal-fired boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) carried out an intensive investigation, one by one registration. The city basically eliminated 35 tons of steam per hour of coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment, coal-fired facilities, no new 35 tons of steam per hour of coal-fired boilers; 35 tons of steam per hour and coal-fired boiler above (except boilers fired power plant) all meet special requirements emission limits; allowed to remain 65 tons of steam per hour coal-fired boiler and above all the complete energy transformation and ultra-low emissions within the city. County (city) district, zone one by one before the end of June 2019 to develop low-nitrogen combustion rehabilitation programs for existing gas boiler, complete combustion of low nitrogen transformation in this area of ​​existing gas boiler before the end of 2019 more than 50%, before the end of 2020 transformation is substantially complete; after transformation principle NOx emission is not higher than 50 mg / m, and comply with appropriate safety boiler specification. Urban built-up area of ​​ultra-low emission biomass boilers implement reform.

A bunch of factors that cause pressure cast iron 8t coal boiler industrial fully automatic georgia efficiency China have occurred in high-profile coal to natural gas operation, cast iron boiler should be transported, greatly avoid dust contamination, smoke and harmful gases such as nitric oxide are also under control. Efficiency is the key measure of regular cast iron boilers, let you research a bunch of factors that cause the cast iron boiler efficiency under pressure. Through the study of relevant departments, cast iron boilers heat loss is mainly due to bear with these two places: the proportion of full combustion air flue gas emissions related to unreasonable waste heat. Reduce flue gas emission waste heat boiler can be installed in a cast iron terminal fume fever recycled back into the formation, or should be shipped condensing boilers more advanced functions. Combustion air ratio sufficient unreasonable unsuitable Summary: ejector ordinary cast iron boiler burner, air-formed flexible scheduling can not occur. Many non-automatic blower cast iron boiler burners, creating factors that cause unreasonable fuel ratio are the following: the main air-fuel ratio unreasonable inclusion can be divided into two conditions: when the airflow excess, having endless excess cool air is heating, creating a cast iron boiler operating costs increase, reduced cast iron boiler efficiency; when the airflow of non-compliance, will reveal the phenomenon is not completely lit, cast iron boiler efficiency appears weakened.

Several countries because of pressure cast iron 8t coal boiler industrial fully automatic georgia efficiency indicators have been carried out in a blaze of glory roaring coal to gas work, use cast iron boiler, greatly minus the dust of the infected, and dangerous gases such as nitric oxide smoke It has been suppressed. Efficiency index is a measure of the key rules of cast iron boilers, here we come to discuss under pressure cast iron boiler efficiency indicators of several reasons. After research stakeholders, cast iron boilers heat loss stems from two main places: the loss of full combustion air ratio unreasonable and smoke exhaust heat. Heat loss can be reduced smoke emission can be converted flue gas heat recovery boiler of cast iron fitted in the tail, or selection of more excellent function FGR boiler. Fully air combustion ratio does not meet the criteria unreasonable Summary: ordinary cast iron boilers ejector burner, resulting in air-fuel ratio can not be motorized mobility. Many cast iron boilers are mechanical draft burners, resulting in an unreasonable fuel ratio because of the following: the main air-fuel ratio unreasonable case two types: when too much air, not having excessively low temperature air is heated , resulting in cast iron boiler energy costs rising, cast iron boiler efficiency index weakened; when there is insufficient air, insufficient burning situation occurs, resulting in cast iron boiler efficiency indicators weakened.

Biomass fuel in CFB 8t coal boiler industrial fully automatic georgia analysis

Biomass is a kind of fuel that is more and more often used in the energy industry. It supplements coal and allows it to meet the requirements of producing “green” energy and limit CO2 or sulphur emissions. Research refers to the ash originated from the combustion of the lignite with and without the wood biomass in the CFB boiler. This article shows the results of research into physical-chemical properties of fly ash obtained from the combustion of the lignite with and without the wood biomass (wood pellet). The possibilities of the use of this ash include in suspension technologies widely used in coal mines.
