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 boiler 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.

The boundaries of the boiler and large boilers and boiler combustion method usually used in home heating or bathing more, there is a small naturally large boilers, both of which boiler has a very clear difference, even the demarcation has many new the user does not make equipment for combustion, the following'll tell you about methods of water and fuel demarcation between the two: First, the demarcation of large and small boiler boiler boiler capacity according to the size of the boiler has a large, medium, small of points, but there is no fixed, definite boundaries between them. With the development of China's power industry, power plant boiler capacity is increasing, and the boundaries of the capacity of large and small boilers will continue to evolve, from the current situation, the generated power is equal to or greater than 300MW boiler unit configuration for large boilers. 1T is bounded by Second, the correct combustion method, the water fill, fill the tank to keep less than half tank of water. All the radiator bleed valve deflated until the water --- pay attention to add water. 2, the briquettes ignited on the gas stove, coal stove put in --- must take the good eye. 3, the pressure of coal, opening the damper. 4, Kai furnace few days to wash bleed radiators, Qin replenishment. In fact civilian life boiler boiler, its small size, low power consumption, a typical feature is suitable for home use. Two kinds of boiler From outward appearances it seems like, in order not to confuse, we have to remember their boundaries, to master the correct combustion methods help us to secure the future use.

Coal-fired boilers into gas-fired boilers, there is no obvious advantage: the use of coal energy is larger proportion of the amount of primary energy, but with the continuous strengthening of energy saving policies, many of them need to be high-quality boiler transformation process, alternative out pollution is serious and complex operation of coal-fired boilers to meet environmental requirements. In situations of strong proponent of environmentally friendly low-carbon, high-efficiency low-pollution coal-fired boilers into energy-saving and low pollution emissions from gas-fired boilers, will be the inevitable trend of social development, then, after coal-fired boilers into gas, which obviously advantage? 1, first of all, the transformation of coal-fired boilers to gas boilers, can significantly reduce pollutant emissions, cleaner and more environmentally friendly. Coal itself there is a great stain resistance, coupled with the combustion process will produce a lot of smoke, but also with environmental contrary; after boiler, natural gas, ash and sulfur content is very low, smoke and dust generated by the amount little to almost nothing better achieve the environmental standards of boiler equipment. 2, secondly, after the successful transformation of the unique boiler can reduce the investment cost of more boilers, because gas-fired boiler is no need to configure a variety of desired soot blower and dust, coal boiler slag equipment, and boiler into gas after the furnace does not require much space for space-saving stacking coal space, but also saves additional auxiliary gas boiler water for dust coal boiler slag and other dust. 3, again, easier to operate gas-fired boiler, gas is transported by pipeline without having to use storage devices can be used directly in the fuel prior to combustion without the need for professional re-processing, coal boilers requires not only professional conveyor track also requires a lot of storage sites and carried out by the need to make better use of coal pre-combustion process can be. 4, after the transformation of the important benefits that reduce the labor intensity. After transformation through boiler can reduce the staff, not the entire gas boiler coal-fired boiler various auxiliary equipment, thereby reducing operator can also save the company costs more, the whole process is not simple physical strength pay.
