powermax carbonization gas boiler
Dongying City, Shandong Province in response to low-nitrogen coal-fired powermax carbonization boilers, industrial waste heat recycling and other environmental policies, combined with local conditions, Dali urban and rural areas to promote clean heating projects, and achieved remarkable results. As of mid-October this year, Dongying City clean heating rate of more than 72%.
Recently, Dongying Municipal Urban Management Bureau to the outside world, in order to further promote the urban and rural clean heating, it has already shut down 10 coal-fired boilers environmental non-compliance of a total of 155MW.
After shutting down 10 coal-fired boilers environmental non-compliance, Dongying City high environmental standards were established in a total of four 58MW gas-fired boiler and a total of four 70MW coal-water slurry boiler through a series of energy-saving treatment, flue gas emissions much higher than the index of new environmentally friendly ultra-low emission requirements.
Meanwhile, Dongying City, the original heating effect is also unsatisfactory 4.33 million square meters of heating regions to establish a uniform heating systems, and the use of standards to ensure clean heat source; higher operating costs for the original 2.17 million square meters of heating area heat source replacement process, both to ensure good heating effect but also saves a lot of money.
According to statistics, this year the city of Dongying city plans to add a total area of clean warm 8.1138 million square meters, down to the next new clean heating in rural areas 45000.
Recently, Dongying City issued a "Dongying City 2018-- 2020 coal consumption reduction alternative work" (the "Program"), after the completion of the city's 10 steam tons / hour and small coal-fired boilers zero and start steaming for 35 out of work t / h coal-fired boilers and, as of 2020, out of 35 steam tons / hour and coal-fired boilers.
Burner fuel gas selected selection principles which fuel gas powermax carbonization boiler burners should be based on structural features and performance requirements of the boiler body, in conjunction with user conditions, making correct comparison, several general principles according to the following options: 1) according to user selection of used fuel type, liquid fuel kerosene, diesel oil, heavy oil, residual oil and waste oil, fuel gas city gas, natural gas, liquefied petroleum gas and biogas, fuel should have the necessary analysis of data used: ① kerosene, diesel should have heat and density. ② heavy oil, residual oil and the viscosity should, heat, moisture, flash point, mechanical impurities, ash, freezing point, density and the oil temperature. ③ should calorific gas, gas pressure and density. 2) to select the type burner nozzle atomization method or the gas burner and the furnace structure according to the performance of the boiler. 3) the burner output should match the rated output of the boiler, choose a good shape of the flame, such as length and diameter so as to adapt the furnace structure. The required combustion air is supplied from the root flare fuel gas and air or oil mist uniformly mixed rapidly, to ensure complete combustion. The rated output of the boiler and boiler efficiency is determined, the fuel consumption is calculated, and then selected according to power a single burner arranged to determine the number of burners. Increase the number of burners, in favor of the atomization quality assurance wind oil mix, but too many, and not easy to operation and maintenance, will give burner arrangement difficult. 4) adjusting the burner to a large extent, be able to adapt to changes in boiler load, to ensure complete stable combustion under different conditions. 5) fuel atomization less energy consumption, adjusting the wind resistance of the device to be small. 6) Effects of noise and smoke emission must comply with environmental standards, mainly emissions S02, CO and NOx must be lower than the predetermined country, should use low NOx burners and low noise. There are integral and split two 7) a burner assembly embodiment. I.e. monolithic burner body, the burner and a combustion air blower system (including an oil pump, a solenoid valve, a servo motor or the like) into one; split i.e. burner body (comprising a combustion head, oil or gas systems), fans and combustion burner control system (including the control box, fan thermal relay, AC contactor, etc.) are each independent three-part system, according to the specific requirements of the boiler and user choice. Simple 8) should be used in construction, reliable operation, easy to adjust and control the repair, easy to implement automatic control of the combustion process in the burner. 9) to deal with the burner brand, performance, price, and service life of comprehensive comparison. 10) In addition to the burner air pressure to overcome the resistance of the boiler body considered, but also to overcome the resistance and flue gas economizer system.
What is the difference between the gas powermax carbonization boiler and coal-fired boiler? Whether gas or coal can be used as fuel for boilers, however, named according to the type of fuel used for different boilers are not the same, so there is such a different type of gas boilers and gas boilers. So both types of boilers in addition to the fuel used in the combustion is not the same, between the coal-fired boilers and gas boilers, what difference does it make? 1, fuel is coal flue gas of coal-fired boilers used in different, when coal combustion will have a greater smoke caused serious pollution to the environment, however, high stability of the gas after combustion boiler did not smoke exhaust, because the basic gas on can be completely burned, toxic black smoke can reach zero ringelman level, SO2 content of which is very small, so there is no pollution to the environment. 2, different heat loss in order to allow coal-fired boilers to maintain sufficient combustion efforts require the use of human or other device to stop adding coal-fired furnace, when the need intermittent operation, it takes a long time to start to increase again furnace temperature, it will generate a lot of heat when the pressure of the fire damage, while the gas boiler is very easy to start and stop, fast heating intermittent operation, thereby reducing heat loss in this process. 3, different treatment after burning coal combustion in the boiler will produce large amounts of ash, in order to maintain a good healthy environment need to transport ash to the professional field slag processing, however, gas-fired boiler using gas , there will be no remaining after combustion ash, there is no need to process it, not only to avoid environmental pollution also reduces the labor intensity and the amount of urban ash storage and transportation companies. This is more than some of the differences between the three coal-fired boilers and gas boilers. By introducing the above we can understand the essential difference between the two boilers can understand, it is because of gas boilers more environmentally friendly energy was gradually replace coal-fired boilers. However, if companies need to use this boiler, in order to advance understanding of the security needs of gas-fired boilers which have quality assurance.
Not the indoor air clean, but also to contribute their efforts to reduce the haze of it. Using electric powermax carbonization boilers, not only saves space, but also as a make beautiful furniture, beautiful and seductive. Electric boiler, electrical energy is directly converted into heat energy, fast heating, thermal conversion efficiency is close to 100%. With conventional heating methods is very significant energy saving effect. Electric boiler to meet intermittent heating, the temperature of the room thermostat can be detected, so that the indoor temperature gradually changes, obvious energy saving effect. Low operating costs electric boiler, electric boiler heating encourage full use of national electricity policy. Operating costs compared to other air conditioning equipment, gas and other cheaper by 20% -40%.
