Coal Fired Steam Boiler Price For Farm Heating

Steam boiler buying guide and cautions because the coal fired steam boiler price for farm heating is an extremely easy to use and very clean and environmentally friendly boiler, so it is widely used in various fields, and very loved by the people. We buy when the steam boiler, it must first be checked in detail, to see its various parts is normal, and make sure it's good quality. From the perspective of traditional economic and energy structure of China's point of view, gas boilers due to the low one-time investment costs of popular people favored, especially in the rich coal resources, environmental protection and less demanding areas people prefer to select it. But in resource-poor coal, coal prices are not low areas of oil, gas and coal compared to a certain competitiveness. Another reason people like coal stove is easy to operate. But gas-fired boiler pollution: waste, emissions, waste water, "three wastes" and taste, governance Yijiao difficult (especially desulfurization, the current gas boiler desulfurization technology has made some achievements, but the high investment costs, operation complex, large area) from a social perspective should limit the use of gas-fired boilers. Gas boilers efficient, clean, environmentally friendly, without manual operation, only need to monitor, small footprint, no need to transport fuel, no need to deal with soot, due to natural gas combustion no impurities, no corrosion damage to boilers and related accessories, boiler long life , defined as 15 years, but basically long-term use. Is now mainstream boiler, natural gas is the environmental protection sector, the government vigorously promoted. Many have been using coal as the heat source of industrial companies now use gas stoves geographical mandatory requirements, it may be gas steam boiler threshold will be higher in the future to strengthen environmental protection efforts. Soot emissions from oil-fired boiler, although lower, but its emissions of harmful NOX, SOX gases are causing "photochemical smog" and acid rain culprit, to be governance as soot emissions as gas boiler control. Gas boiler with a small footprint, less pollution emissions advantages, but also the cost of the boiler room is not set up, the use of natural gas fuel prices, operating costs lower than oil-fired boiler. By comparison of three of the furnace, gas boiler not only set a lower cost and operating cost, and its social benefits are incomparable. Natural gas is the cleanest fuel, is the least polluting fuel emissions, gas-fired boilers will be the development trend of boiler final.

To further promote air pollution control tough fight, push the air quality continues to improve, according to "Zhengzhou City, the 2018 campaign of air pollution control plan" and "Chung Dong New Area, the 2018 campaign of air pollution control plan" requirements, the area to carry natural gas boiler low nitrogen renovation work, hereby notify the relevant issues as follows:

(1) before the end of September 2018, Eastern 4 tons of steam boiler and above the implementation of low-nitrogen gas engineering construction and renovation. Encourage the implementation of other gas-fired low-nitrogen transformation.

Promote the transformation of low nitrogen gas boiler according to early completion, and more reward principles, decreasing year by year funding award up mode. Before the end of June 2018 to complete the construction of low-nitrogen transformation, the concentration of nitrogen oxide emissions or else higher than 30 mg / cubic meters of gas boilers, carried out in accordance with the award make up 40% of equipment investment; before the end of September 2018, to complete the low nitrogen renovation project construction, the concentration of nitrogen oxide emissions or else higher than 30 mg / cubic meters of gas boilers, carried out in accordance with the award make up 30% of equipment investment; before the end of April 2019 to complete the project construction and renovation of low-nitrogen, nitrogen oxides Or emission concentration higher than 30 mg / cubic meters of gas boilers, carried out in accordance with the award make up 15% of equipment investment;

6 tons adjusting a combustion gas coal fired steam boiler price for farm heating, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.

What is the main difference between a coal-fired boiler and a gas-fired coal fired steam boiler price for farm heating? Nominally, the obvious difference between a gas-fired steam boiler and a coal-fired boiler is that the fuel used is different. The former uses natural gas and the latter uses coal. I think the misgivings of many boiler users are why they should eliminate coal-fired boilers because many have already purchased and used coal-fired boilers. If they switch to gas-fired boilers, it will be a huge expense. Firstly, according to the development direction of China's ecological environment, coal-fired boilers will gradually be replaced by gas-fired boilers or other clean and environmentally friendly energy boilers, and gradually withdraw from the historical stage. Yes. The difference between coal-fired boiler and gas-fired steam boiler is very big, and the main reason for eliminating coal-fired boiler is environmental protection. From the fuel supply part, the gas-fired boiler only needs a pipe to connect to the boiler; the coal-fired boiler requires coal yard, coal (belt or man-made), coal transport, loading and unloading, storage and boiler loading process. It will produce dust, causing serious pollution to people's living environment. From the point of view of atmospheric emissions, the content of dust in natural gas is very small and can be negligible; the ash content of coal is high, and the ash content is about 10% and 30%, which will produce smoke after combustion. If dust removal facilities are reduced, pollutant emissions will be reduced. It will increase; if there are more dust removal facilities, the corresponding costs will increase, which is not a long-term solution. In addition, the sulfur content of natural gas is also very small, coal-fired boiler dust removal, desulfurization and nitrogen removal can be obtained, gas-fired boilers only need to consider the problem of nitrogen removal. From the point of view of other waste emissions, natural gas is basically free of other pollutants, especially urban gas. In the case of coal, coal yards, especially small boilers built mainly in the open air, will produce coal slurry water during the rainy season, seeping into groundwater or sinks. When entering the surface water, the burning ashes are transported to produce dust. Of course, there's a difference in other ways. Different. For small-sized boilers, gas-fired boilers are more energy-saving than coal-fired boilers, with simple equipment flow, small footprint, low operating and maintenance costs, and so on. These are the main differences between coal-fired boilers and gas-fired steam boilers, and the significance of eliminating coal-fired boilers. It can be seen that the use of gas-fired boilers is the general trend of the whole society.
