high quality for 2800 kw gas boiler
When customers need to buy oil and gas high quality for 2800 kw boilers, they need to know the boiler capacity that they need. Because the boiler will consume a lot of fuel during operation, the boiler capacity will cause unnecessary losses and increase the boiler cost.
Burner fuel gas selected selection principles which fuel gas high quality for 2800 kw 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.
2019, Nanjing for more stringent ozone pollution, for volatile organic compounds, governance and control measures nitrogen oxides unabated.
Nanjing Ecological Environment Agency staff members at atmospheric introduction, with the recent temperature increases, there has been a trend in some parts of ozone exceeded. This summer, the environmental protection department will introduce stricter air pollution control measures, starting from the two aspects of governance volatile organic compounds and nitrogen oxides to reduce ozone pollution.
It is understood that Nanjing will be completed this year 44 companies VOCs governance and thermal power, cement, bricks and other building materials industries fugitive emissions-depth treatment in the city in batches with a gas-fired boiler 936 units, the implementation of the nitrogen oxides governance Sector Engineering; city station 475 to achieve ultra-low emission particulate biomass boilers, for the privately polluting fuels blended biomass boilers embodiment eliminated. It is worth mentioning that the revised "Nanjing Atmospheric Pollution Prevention Act," to be implemented next month. Among them, organic solvents, paints use, as well as volatile organic compounds corporate governance and management have put forward new demands.
Gas high quality for 2800 kw boilers and coal-fired boiler, what is the main difference: coal-fired boilers and gas boilers are more types of boilers currently on the market use accounting, many users in the choice of boiler equipment, I do not know which type of selection is better. Today, fast boiler come to you summed up the difference between the three main gas boiler with coal-fired boilers. 1, different exhaust fuel fired boilers using coal, will produce soot after combustion, ash, sulfur grading smoke more, these fumes are causing serious environmental pollution. Gas boiler using natural gas as a fuel, because of its high stability, but no smoke after combustion is discharged, because the gas can be substantially complete combustion of harmful substances ,, which is very small, so there is little 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 in the boiler will produce large amounts of ash after combustion, in order to better maintain the quality of the environment, the need to transport the ash to slag professional field for processing. Gas-fired boiler using natural gas this matter, there will be no residual ash after combustion, 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.
