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 for paper factory 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.

CBM 1 ton wns series oil and gas boiler for paper factorys can use natural gas, light oil and other fuels, high combustion efficiency, and the natural gas consumed per hour is about 79.4Nm³, which is an energy-saving product. Our company can provide boiler auxiliary equipment, and give specific plans according to customer needs, and quote accordingly.

Comparison of coal-fired steam boiler for paper factory and gas steam boiler? Which is more cost-effective? There will be new users are asked coal-fired steam boiler and gas steam boiler which is more cost-effective in a number of economic operation? Believed to be ready to buy a steam boiler of every business relationship or personally, with you today, I will work together to analyze these two boilers in operating costs to do a comparison. First, the first point to analyze procurement costs: Because gas steam boiler in the annex above techniques and configurations to be clear lead and coal-fired steam boiler, gas steam boiler supporting a dedicated burner, put the cost of just one burner price opened, so that the same tonnage of steam boilers, steam boilers high gas prices than coal-fired steam boilers and more. The second point to analyze construction costs: The costs mainly from the boiler room, boiler tubes of steam investment funds. Where the coal-fired steam boiler because more appropriate auxiliary equipment, so in the boiler room construction funds to be more. There is a gas steam boiler automatic control operation, and automatic alarm and automatic protection function. Connected to the gas pipeline, the burner will automatically supply costs can effectively save staff. Coal-fired steam boiler because of the need of coal on the program, so in terms of personnel expenses wage will be larger. The third point to analyze the environmental cost: major review means that the coal-fired steam boilers now more stringent. The gas steam boiler due to the operation of the economy, environmental protection and energy saving, as well as government policy to encourage more and more widely used. The fourth point to analyze the cost of fuel: coal-fired steam boiler will be much higher than the steam boilers in gas fuels. After analyzing the above four points of view on coal in order to save operating costs more than gas steam boiler steam boiler, but coal-fired steam boiler steam boiler environmentally friendly than gas in environmental protection, environmental pollution is now increasing in recent years, so the state to environmental pollution control is relatively strict, so in accordance with the requirements of environmental protection point of view has an advantage gas steam boiler.

Factors affecting the energy saving heating boiler for paper factorys What are the reasons 1, strictly control the temperature of the boiler exhaust gas boiler heating some of the heat loss, exha reduce flue gas heat loss is an effective way to achieve energy-saving heating boilers. There is a certain temperature difference between the outdoor air temperature and the exhaust gas temperature. When the outdoor air temperature is lower than the exhaust gas temperature, exhaust heat loss is generated. Accordingly, the heating boiler exhaust gas temperature should be strictly controlled within the controllable range. If the exhaust gas temperature is too high, if the exhaust gas temperature is too low may increa, it will lead directly to the heating boiler running cost increases, which is due to the increased tail heating surface, so that the exhaust gas temperature as low as possible. In the energy saving work boiler should be carried out technical accounting and economic accounting. Accounting based on the dew point of the smoke, the tail heating surface and heat loss due to the consumption of the metal. 2, the carbon content of the slag reduce heating boiler First, the operation of the heating boiler in order to ensure the heating boiler that burns coal, the coal particle size be controlled, full use of coal resources, while achieving the purpose of protecting the environment. Secondly, reasonably boiler operating parameters adjusted to reduce the carbon content of the slag, that the ratio of coal to air is more reasonable and the coal before combustion in the furnace. Furnace temperature is a key factor in the index reflects a lot of energy-saving operation of the boiler. The carbon content of slag is one of them. In order to ensure energy saving heating boilers, efforts should be made to reduce the carbon content in the slag, timely elimination of negative factors affecting the normal combustion boiler. 3, the outer surface of the boiler furnace control temperature of the boiler size of the heat affected second two factors is the temperature of the boiler outer wall. It is also important for the outer wall temperature of the boiler, the influence of the external surface temperature of the boiler heating boiler. Relatively larger exterior wall area, the higher the temperature of the external walls, the greater the amount of heat to the surrounding environment. To reduce the heat radiation loss of a boiler, the boiler must be controlled outer surface of the body temperature. 4, to improve the thermal efficiency of the thermal efficiency of the heating boiler heating boiler is a comprehensive index of energy-saving measures. Improve the thermal efficiency of heating boilers, but also help to improve energy efficiency and heating boilers. Improve operational level boiler operator, control of boiler operating conditions, timely maintenance heating boilers, heating boilers to save energy. 5, timely monitor the operation of heating boilers timely monitoring of the operation of heating boilers, not only improve the operational efficiency of the boiler, environmental protection can not be underestimated. Different boiler room should take different measures, timely monitoring of the operation of heating boilers. Spread the boiler room should be checked by installing equipment, computer monitor should focus boiler room.
