Electric Water Heater And Gas Boiler


Electric Water Heater And Gas Boiler

Why gas steam electric water heater and gas boiler energy saving may be why gas steam boiler energy saving gas steam boiler design pressure should be slightly higher than the high work pressure, and not less than safety valve opening pressure. Design pressure gas furnace using 1.2 to 1.5 times the working pressure; liquid pressure furnace design should take pressure of 1.05 to 1.2 times; Liquid furnace gas and steam outlet pressure differential should be greater than 0.15MPa (1.5kgf / cm2). Temperature gas steam boiler import and export, from the design of both economic and security point of view, to design gas-steam to run a suitable temperature difference in the system, this temperature difference should be less than 30 ℃. Gas steam boiler is a closed loop, the return oil temperature and oil temperature only a 20-30, 20-30 words, only heating the temperature difference can reach temperature gas steam boiler. The steam boiler is added to cold water, the cold water is heated into steam to heat heating device, steam becomes condensed water discharged 60-70 degrees. Therefore, the role of energy saving functions!

Industrial electric water heater and gas boiler energy saving measures which industrial boiler energy saving measures which first of all, improve boiler regulations and standards. Speed ​​up the boiler, boiler and pressure vessel manufacturing license conditions and modify Management for registration of technical supervision and management of energy-saving regulations, boilers, boiler design document recognition rules, regulations and technical specifications, energy saving and environmental protection index as a boiler manufacturing license, registration, design review compulsory requirements, strict implementation of energy-saving boiler design document review and styling products test system energy efficiency, energy saving, environmental protection, does not meet the safety requirements of the boiler, banning the production, sale and use, improve energy saving boiler threshold. Second, it increases energy-saving technology, new product development and promotion efforts. Key recommendations to improve the structure and level of technology stacks chain furnace exhaust combustion equipment, small boiler gasification combustion technology research and product development, coal-fired industrial boiler control technology research and product development. Development of gas condensing boilers, industrial boilers and energy-saving effect evaluation software audit, accounting boiler energy statistics and analysis system software research and development and other technical development work, through financial subsidies to accelerate the application of high efficiency energy saving boiler. Third, eliminate the old, inefficient boilers. Revision of coal-fired industrial boilers and energy-efficient economic operation, environmental protection and minimum limits of the system. The establishment of the old boilers, boiler inefficiencies out of the update mechanism, instead of a small boiler with a large boiler, instead of the low boiler parameters with high parameter boiler, instead of coal-fired boiler with a gas boiler or biomass boilers in the conditional area, thus greatly improving the energy efficiency. Safety of the boiler. The fourth is to strengthen the transformation of energy saving boiler. To improve the level of energy saving and environmental protection and industrial boilers fired boiler system, the automatic control system of the coal-fired industrial boilers, combustion optimization, heat recovery, frequency control, efficient desulfurization, denitrification and dust removal has been transformed, to improve the fuel water quality coal industrial boilers. Fifth, strengthen energy-saving knowledge management and boiler operators training. Boiler establish user management system, including energy-saving target assessment system, strengthen energy-saving boiler technical training of management personnel.

What is the principle of the electric water heater and gas boiler? 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.
