coal fire boiler portion

A coal fire boiler portion thermal efficiency improve conventional coal-fired boiler mostly thermal efficiency of about 70%, a large portion of the energy due to heat loss or otherwise be wasted, the use of gas boiler after the "coal to gas", the thermal efficiency will be 20% -40% improved. Second, lower investment costs than the price of coal gas prices high, but in addition to fuel costs, only the investment pipeline can. The investment in coal-fired boilers in addition to fuel costs, as well as transportation costs, labor costs, storage costs, the overall price is not cheap. From the cost point of view, natural gas overall advantage. Third, improve environmental benefits due to the combustion of natural gas itself is adequate, and clean burning, non-polluting emissions is a more environmentally friendly energy sources. After coal combustion emissions from sulfur, more ash, environmental pollution more serious, which is incomparable with gas boiler. Gas boiler can bring greater environmental benefits to the enterprise.

How to choose a reasonable price brand of industrial coal fire boiler portions How to choose a reasonable price brand of industrial boilers, fuel gas-fired boiler, good insulation properties, clean and green, the boiler thermal efficiency advantages, is currently popular on the market a boiler in addition to gas-fired boiler has its own characteristics, the full implementation of the national coal policy to further promote gas-fired boiler coal-fired boiler to become the user's preferred furnace, gas boiler market demand continues to grow. There are many brands on the market boilers, boiler quality is not uniform. For users, how to choose the right brand of industrial boilers price is very important. How to choose the affordable brand of industrial boilers, we all know that smoke respirable particulate matter is the culprit, but in fact, another reason - nitrogen oxides can not be ignored. Coal project promotion, gas boilers ownership will continue to increase. Coal combustion gas may reduce the pressure of the coal, to reduce the concentration of airborne particulate matter, nitrogen oxides, but also an important reason for the smoke, which generates an important condition is a high temperature. Gas boiler for heating and the heating temperature needs. Many gas SO2 emissions from large boilers on the one hand is greatly reduced, on the other hand produce large amounts of nitrogen oxides. Fast side gas boiler gas boiler can be reduced to nitrogen oxides emission concentration 30mg / m or less. With the implementation of the new emission standards across the country over the next three to five years to use low nitrogen gas boiler to improve the cleanliness of a large number of industrial buildings and residential heating gas boiler emissions.

To speed up solving air pollution prevention and control Liaoyang key and difficult issues, Liaoyang city government combined with the actual circumstances of the sky to win the Battle of implementation. Details are as follows.

1, promote clean heating. To proceed from reality, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, warm winter to ensure the safety of the masses. In strict accordance with the "Notice on and of" (Municipal Office Liao Fa [2018] 19) requirements, minutes from the town to the countryside level steady implementation of clean coal-fired heating, natural gas heating in an orderly way, actively promote electric heating, heat pump heating scientific development, expansion of industrial waste heat heating, heating to accelerate improvements in the proportion of clean, implement the relevant provincial price policy, ensure the power supply. 2019 Clean heating rate should reach 44% in 2020 to clean the heating rate should reach 49%.

2, control total coal consumption. According to energy-saving emission reduction Work Leading Group Office of the City "on the issuance of Liaoyang control total coal consumption program of work (2018-2020 years)" (City of Liaoning Office Savings Fa [2018] No. 3), the city's total coal consumption do control. Vigorously for shutting down energy consumption, safety, environmental protection and other 300,000 kilowatts coal-fired units of non-compliance, capacity indicators for shutting down the unit, allowing the transaction or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units. In 2020, the city's coal accounts for the proportion of total energy consumption control to 58.6% or less.

3, in-depth implementation of coal-fired boiler control. Increase the small coal-fired boilers (including coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment, coal-fired facilities) elimination efforts. According to the principle of small demolition and Japan to promote clean energy use, developing the approach to co-ordinate the establishment and management of inventory ledger. Strengthen ecological environment, housing and urban construction, industry and information technology, market regulators linkage, strictly control new coal-fired boilers. 2018, 10 steam tons / hour (or 7 MW) coal-fired boilers and focus on the completion of the phase-out of county level and above all the urban area and old inefficient coal-fired boilers small tasks within the industrial park, small demolition boiler mission of 111; 2019, to phase out coal-fired boilers to further improve standards, expand the scope to promote the elimination of urban built-up area of ​​20 steam tons / hour (or 14 MW) and coal-fired boilers, in addition to special planning according to urban heating heating boilers other than essential to retain, urban built-up area 20 steam tons / hour (or 14 MW) coal-fired boilers to be eliminated and all.

4, the development of industrial furnaces governance special action. Development of industrial furnace remediation plan to carry out an intensive investigation, the establishment of various types of industrial furnaces inventory management. Increase the non-compliance of industrial furnaces out of efforts to speed up the elimination of small and medium gas furnace. Encourage industrial furnaces use electricity, natural gas and other clean energy or heat from the surrounding power plant. Key areas banned fired stove, the coal-fired cogeneration substantially eliminated heating pipe network coverage heated oven (furnace); out hearth diameter of 3 meters fuels gas furnace, a fixed bed to increase fertilizer industry intermittent coal gasifier reform efforts; focus on the use of gas furnace industrial park, they will not have to switch to natural conditions, should build a unified clean coal gas central principle; prohibition blended with high-sulfur petroleum coke. The industrial furnace governance as key tasks of environmental inspectors, who have not included in the list of industrial furnaces were included in the autumn-winter peak load shifting production program.

Instead of gas-fired coal fire boiler portion coal-fired boilers has become an inevitable trend of more and more common as the use of gas, China's energy structure has undergone tremendous changes. In the future for a long period of time, gas and coal is still the main source of energy, how to weigh the severity of it in small series for everyone here today about the analysis and comparison:? Although there are many drawbacks of coal-fired boilers, but in the national economic development has an irreplaceable role, he plays an important role in the past for a long time. Because all the advantages of gas-fired boiler, will become a major force in the development of national energy policy boiler. Instead of gas-fired boiler coal-fired boilers has become an inevitable trend. Coal-fired boilers are in a very long time the main products of heating, but there are many drawbacks: such as low thermal efficiency, energy waste, due to the high sulfur content coal, to atmospheric pollution. In recent years, the contradiction between supply and demand of energy and environmental pollution have become increasingly prominent. Compared with coal and gas, is one of the most clean fuel, he combustion, high thermal efficiency, low air pollution, good environmental performance.
