Gas-fired steam mechanical coal steam normal pressure fire tube boiler price and gas steam boiler at any time there is any good compared to the country more and more attention to environmental protection, gas steam boiler has been a great blow, and relatively gas steam boiler by many users of all ages, in recent years, the country also strongly promote the use of gas-fired boiler, gas steam boiler then compared with the gas steam boiler what good is it? And today we work together to explore. Gas-fired steam boiler steam boiler and gas each accounted for half of the market, showing potential rival, but in the long run, gas steam boiler will obviously be the only dominant market. Do not believe, look! 1. Purchase costs: gas boiler is evident in the technical and auxiliary facilities are far ahead of the gas boiler, and it is equipped with a special gas burner. 1 steam boiler tonnage, for example, the price of gas than the gas boiler boiler on high about 30%. 2. Construction costs: The costs mainly from the boiler room. Because the corresponding auxiliary equipment more gas steam boiler, the boiler room in the building have a little more money. The gas boiler auxiliary facilities require little or automatic control and operation, and automatic alarm and automatic protection, not only save building costs, but also safe and reliable; Also connected to the gas pipeline, the burner will automatically supply gas can effectively save costs staff. The gas-fired boilers because of the need of coal on the program, so it needs some staff payroll. 3. Fuel cost: around this by looking at the actual specific fuel price can be clearly seen. The fact is that the amount of gas than the gas burned per hour for much more. 4. environmental costs: in the need to protect the environment, review the current gas boiler more strict. 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.
How to improve the energy efficiency of industrial mechanical coal steam normal pressure fire tube boiler prices 1, focusing on the transformation of practicality (1) above to recover waste heat can be effectively used. For example: high temperature organic heat boiler flue gas, but the process does not require the production of steam and hot water, attention should be considered heated by flue gas waste heat recovery techniques combustion air. (2) improved gas boiler should focus on energy-saving technologies improve the automation level of combustion control, precise control of the combustion state. (3) Consider first the application of energy-saving technologies and sophisticated equipment. 2, considering the technical nature to further improve the thermal efficiency of industrial boilers, it is necessary to consider new energy-saving technologies and equipment. Advanced (1) energy conservation technology and equipment, difficult to implement. Such as: waste heat recovery heat exchanger and the new technology: heat pipe technology, the condensed waste heat recovery technology; new water treatment device: microbial fouling and electromagnetic processing techniques (e.g., hydraulics); combustion automatic control technology. (2) spraying pulverized coal combustion technology (stratified combustion mode and suspension-fired boilers) design, construction and operation of high demand management, oxyfuel technology, such as high temperature air combustion technologies require large investments. 3, forming a complete transformation handle (1) must be considered boiler energy saving, heat insulation of synchronization is complete, sealing, and improved methods of burning fuel adjustment, and the fuel air distribution system of the inverter, reduced nicotinamide tube improved resistance to treatment. (2) pay attention to clean the boiler heating surface, and providing technical improvements boiler water, slag, ash, etc., to ensure that the boiler has good heat transfer properties. (3) the necessary training for technical operations and daily management of energy-saving equipment.
What is the principle of the mechanical coal steam normal pressure fire tube boiler price? No matter how much the tonnage, the boiler works basically the same. Role of the boiler fuel chemical energy is converted into thermal energy, heating and heat inside the pot with water to become superheated steam having a mass and a sufficient amount (steam temperature, steam pressure) of the steam turbine for use. Now the power plant boiler capacity, high parameters, technical complexity, high levels of mechanization and automation, the main fuel is coal, and coal prior to combustion of pulverized coal first made, and then into the boiler combustion heat release in the furnace. Broadly speaking, the work process is the main boiler fuel combustion, heat transfer, vaporization and heating of the water with the superheated steam and the like. The entire boiler boiler composed of two parts and auxiliary equipment. Boiler: boiler body is the main part of the boiler equipment, is composed of two parts, "pot" and "furnace" composition. "Pot" is the soda system which main task is to attract the heat receiving fuel discharged, the water is heated, evaporated and finally becomes superheated steam having certain parameters. It consists economizer, the drum, the downcomer, the header, water wall, superheater and reheater connecting pipes and other equipment and valves. 1) economizer. Vertically positioned rear of the boiler flue, the use of flue gas waste heat boiler feed water, reducing the exhaust gas temperature, increase boiler efficiency, fuel economy (2) drum. At the top of the boiler, it is a cylindrical pressure vessel, which is under water, the upper portion of the steam is that it accepts the economizer runoff, while the downcomer composed header, Wall water circulation circuit. Wall water absorbs heat generated in the soda mixture was collected in the drum, conveyed by the saturated steam to the superheater steam-water separator (3) downcomer. Water supply pipe water wall, the effect of which is introduced into the water in the steam drum to the lower header redistribution respective waterwall tubes. Dispersion in small diameter and the large diameter downcomers Downcomer two kinds. Small diameter tubular small diameter drops, the water cycle of negative (4) waterwall lower header. The main role of the header is a mass pooled or working fluid through the header to the header redistributed through other conduits. A water wall is thicker lower header tube closed at both ends, its role is connected to the downcomer and the water-cooled wall, so as to function together, mixing, redistribution effect working medium (5) water wall. At the furnace around its main task is to absorb radiant heat of the oven, to evaporate water, which is the main heating surface modern boilers, while protecting the furnace wall (6) superheater. Its role is to drum saturated steam into superheated steam on heating (7) having a predetermined temperature reheater. Its role is done in the steam turbine power section is heated up again, and then continue to work in the steam turbine. "Furnace" is the combustion system, its task is to make the fuel burn in a good furnace, heat. It consists of the furnace, the burner, ignition means, air preheater, the smoke duct and the furnace wall, frame and other components. (1) furnace. It is transferred from the furnace wall and into the water wall for fuel combustion, the fuel combustion in suspension, the release of large amounts of heat within the space. (2) burners. Located on the furnace walls or corners, its role is the fuel and air injected into the furnace at a constant speed, so that it can be well mixed in a furnace in order to ensure timely ignition and rapid and complete fuel combustion. DC sub-burner and swirl burner two basic types. (3) air preheater. Located in the boiler backpass, whose role is to use waste heat of flue gas to heat the fuel required for the combustion air, exhaust gas temperature can be further reduced not only, but also for strengthening the furnace combustion, improve the economy of combustion, pulverized coal drying and conveying is advantageous of. Boiler efficiency can be increased by 2%. And rotary two kinds of charge. (4) smoke duct. From the furnace wall is a pipe, the pipe heating surface and the portion of the tube wall and other components of the package, for guiding the flow of flue gas through the heat exchanger and the respective heating surface, and is divided into horizontal flue backpass. Auxiliary ventilation apparatus comprises auxiliary equipment (delivery, induced draft fan), a fuel transportation equipment, milling system, in addition to ash and dust removal equipment, desulfurization equipment.
