9709 chain grate boiler coal burning rule
Several factors underlie the vertical steam 9709 chain grate boiler coal burning rule efficiency China has been working to catch on coal to natural gas, vertical steam boiler with greatly reduced contamination of dust, smoke and other effects of a nitric oxide gas has also been healthy curb. Efficiency is an important indicator of a measure of vertical steam boiler, a good number of factors under the topic to discuss the direct impact of vertical steam boiler efficiency began. After analysis of stakeholders, heat loss from vertical steam boiler contains two pieces: the proportion of full combustion air with flue gas emissions unreasonable heat loss. Heat loss can be reduced smoke emission can be installed at the end of the vertical steam boiler stack waste heat reuse install, or more leading system with condensing boiler. Combustion air ratio sufficient unreasonable faults into: general vertical ejector-type steam boiler burner selection, resulting in a motor fuel ratio can not be adjusted. Most of the selected vertical steam boiler is mechanically strong emission combustion engine, air-fuel ratio resulting irrational factors are the following: air-fuel ratio can be divided into two reasonable chance comprising: when the air in excess, the excess will have full cold It is heated, resulting in increased operating costs vertical steam boiler, steam boiler efficiency vertical drop; when the air is not enough, will produce insufficient burning phenomenon, caused by vertical steam boiler efficiency.
Combined with China's various policies, both from an economic point of view or the point of view of environmental protection direction, to develop gas-fired 9709 chain grate boiler coal burning rule is a clear trend, fast boiler has a lot of experience in the boiler Case "coal to gas", after the transformation of gas boilers whether harmful emissions or fuel utilization, have significantly improved. Help your business better production needs of life.
Since last year, the city of Yinchuan in Ningxia to develop clean energy alternative to coal heating work carried out, in order to adhere to the use of waste heat energy-based heating system, two years, a total removal of 212 coal-fired 9709 chain grate boiler coal burning rule units, designed over 20 million square heating area Meter. At present, Yinchuan City, the formation of a waste heat recovery and cogeneration-based, clean energy co-existence of a new pattern of heating, coal heating gradually withdraw from the stage of history.
According to Yinchuan City Housing Construction Bureau feedback, early last year, Yinchuan City, began to promote the implementation of "East of the West to give a" heat of long-distance heating projects, the long-distance transmission projects across the Yellow River, the basic realization of restructuring heat source, heat source interconnection point to ensure the city heating security and stability, environmental protection is of great significance.
At present, "East of the West to give a" central heating heating net charge of the project, the city branch, etc. have been completed, the east, the city water pipe network has been completed and started flushing cycle, is west of the water, water totaled 145,000 cubic meters.
At the same time, Yinchuan City, also build a heat source, thermoelectric Xixia complete the second phase of construction, the new 2 sets of 350,000 kilowatts supercritical coal-fired air-cooled heat generators, which can effectively replace Yinchuan City, 154 small coal-fired boilers, the annual generating capacity 3.85 billion kwh, heating capacity of 16.42 million square meters.
This year Yinchuan new cogeneration district heating area of 41 million square meters, the new heating pipe network 86 kilometers, is the largest investment project ever central heating, with the largest of the year.
Coal-fired 9709 chain grate boiler coal burning rule to gas boiler advantages: China's major coal-fired boilers used to be the life of heating and industrial boilers being used. Total annual use of coal because coal-fired boilers consumed 600 million tons. According to incomplete statistics, China's total industrial coal-fired boilers is 60 million units. Visible large proportion of coal-fired boilers in China's industrial life, the breadth of coverage. The thermal efficiency of the boiler runs produced generally much lower than the gas boiler, emissions has doubled. Therefore, the transformation of coal-fired boilers to gas-fired boiler is imperative. From central to local government organs at all levels to join all the positive trend of the gas boiler of them, in order to reduce emissions, improve production efficiency to do their part.
