Advantages And Disadvantages Of Coal Module Boiler
Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new advantages and disadvantages of coal module boiler equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).
Henan district heating gas advantages and disadvantages of coal module boiler heating characteristics and uses of a cell or several cells share one building gas boiler room heating using the secondary heating network, an intermediate heat transfer station, the larger the size of the external heating network. Heating area up to several million square meters of high-altitude emissions fumes. 1, Henan area gas boiler heating system to the Characteristics of A, using the advantages: gas boiler Henan province invested more decentralized heating, can achieve centralized management, easy maintenance and users can achieve high-altitude emissions of pollutants. Coal to gas project, you can use direct existing heating systems and boiler room ancillary equipment, saving the initial investment. B, there is a drawback: the thermal efficiency is relatively low, and heat transfer stations outside the network heat losses and the heat medium conveyance power consumption, high emissions of pollutants, the system adjustment is not flexible, large investment outside the network, does not solve the problem of direct measurement of the heat. In the beginning of the construction of the system utilization is low. The end of central heating systems without measurement and adjustment means. Flat Rate according to heating area. Hydraulic imbalance caused by high temperature heating part of the user, when the room is overheated, the user typically using cooling method fenestration adjust the room temperature, resulting in 8% to 15% of the heat loss. Particularly in the construction of mixed use of different nature, according to the same level of heating, because no means of regulation, office buildings, schools and other heating at night and holidays, the hotel was no usual heating, waste of energy. 2, Henan gas boiler gas consumption due to heat loss outside the network is greater than the dispersion of Henan gas boiler heating, the heating temperature is higher than the average gas boiler single-family household heating Henan, Beijing heating in the gas consumption index 10-14m3 / m2. Gas consumption is mainly due to heat loss and heat transfer stations outside the network than other reasons for the high two ways, hydraulic imbalance serious nature of the use of different architectural mix caused by heating. 3, the heating system uses the ground region Henan gas boiler pollutant concentration requirements more stringent, while heating the dispersion concentration of pollutants discharged warm floor exceeded, central heating may be employed. However, there are requirements for stack height shall be determined through calculation. Rarely used in Europe and North America gas central heating boiler area, or are generally thermoelectric cooling and power generation.
Five combustion characteristics of gas combustion in The five main combustion characteristics of gas combustion of Fangkuai environmentally friendly gas-fired advantages and disadvantages of coal module boiler in recent years, many cities frequently occur haze, which has aroused wide concern and heated discussion in the society. China is in the period of energy structure adjustment, the task is imminent, the situation is also very serious. The energy-saving and environmental protection gas-fired boiler of Fangkuai boiler is the time to show its good energy-saving effect and excellent environmental protection ability. More and more favored by enterprises. Next we analyze its advantages from the combustion characteristics of gas fuel. Gas fuel is an efficient, clean energy source, its ignition temperature is relatively low, flame can spread rapidly to each furnace. Local, rapid combustion, easy to achieve automatic gas transportation, mixing, combustion process, mainly have the following characteristics: (1) pollution is almost zero combustion characteristics, plus basically will not produce ash, The nitrogen and sulfur contents are much lower than those of coal and oil fuels, and the amount of dust contained in the flue gas produced by combustion is also very small, which is very conducive to the protection of the environment and is basically a pollution-free combustion mode. Even the areas with the strictest environmental protection requirements can be safely used, at the same time, gas fuels are piped to transport, do not produce ash, transport, storage will not occur in the process of harmful gas leakage, dust pollution and noise pollution. (2) it is convenient to adjust the combustion. The way of transportation of fuel gas is pipeline, which can adjust the gas consumption, adapt to the change of load quickly, and realize low oxygen combustion by adjusting the valve and air valve. Thus improve the thermal efficiency of the boiler. (3) good workability. Compared with oil fuel, gas fuel is piped and supplied directly, eliminating oil storage tank, daily fuel tank and other components. In particular, compared with heavy oil fuel, save heating, heat preservation and other links. Gas system is relatively simple, operation and management is relatively convenient, easy automation. (4) easy to adjust heat. Combustion liquefaction When LPG is added, adding part of the air can not only avoid part of the explosion range, but also adjust the heat generation. (5) Gas fuel also has some shortcomings, when mixed with air to a certain proportion, it will form explosive gas. And most of the components of gas fuel are asphyxiating or toxic to humans and animals, so the safety requirements are very high. The Fangkuai boiler attaches great importance to the safety of energy-saving and environmental-friendly gas-fired boilers, and strictly guards the quality level during production and commissioning. There will be no safety accident as long as there is a code of practice in the process of use. At the present stage, China is vigorously promoting the coal-to-gas project to return the people to a blue sky. . Enterprises have responded to national policies and assumed social responsibility. Warmly welcome you to our Fangkuai boiler to buy energy-saving and environmentally friendly gas-fired boiler.
1, should guarantee the smooth flow of flue gas, have a good fullness and should avoid dead ends and dead.
2, the burner should be provided at the height position of the center of the furnace, and the combustion space and has sufficient length. Flame should not be flushed to the wall heating surface, so as to avoid incomplete combustion gases local overheating and damage to the wall.
3, since the combustion gas in the furnace backlash, high thermal strength, exposed to the bottom of the drum in the furnace should be adiabatic process.
4, various pipes, fire tube boiler furnace wall substantially refractory brick masonry, and shield plus insulation material. In the "coal to gas" should pay attention to the tightness of the furnace wall, minimizing the original door, door checks, etc., can assemble the refractory block, prevent cold air flames wounding or excessive leakage into the furnace , affecting boiler efficiency, to see the fire hole must remain closed also should see the fire hole, heat-resistant glass viewing by fire.
5, the furnace boiler and gas than coal-fired boilers, is generally greater, there is sufficient combustion space, increase the volume of gas, does not affect the transformation of combustion conditions. If the user requests output significantly improved boiler, the furnace can be increased radiation heating surface, to remove scale and soot while the inner surface of the outer heating of the original, so that without increasing the volume of the boiler case to improve the boiler output is not a problem. Thermodynamic calculations must do in the boiler, while the smoke but also good wind resistance calculation intensity calculation.
