Automatic 1Mw Gas Industrial Hot Water Boiler

Principles of steam boilers and solutions hydraulic external gear: told you about the principles of steam boilers and solutions for steam boiler hydraulic external gear in accordance with the fuel (electricity, oil, gas) can be divided into electric steam boilers, oil steam boiler, gas steam boiler three kinds; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler compact than a single, double return of the vertical structure, a large steam boiler plurality of three-pass horizontal structure. If the classification according to top standards, in the form of steam boilers on the lot, would like to give an ordinary packaged boiler say four tons vapor. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Steam boiler combustion section and drive means by a chain grate, a combustion chamber together with the pan rack frame formed on a grate composition. Four weeks envelope refractories.

What is the principle of the 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.

At the end of 2017, China Guodian is located in Jiangxi Province Wanan Hydropower Plant After evaluating the situation, some of the steam boiler used to purchase much-needed daily work. Sales Manager fast boiler combined with the actual situation of the power plant for its recommendation 2 0.5 tons of electrically heated steam boilers.

Hot water boiler fuel classified according to different automatic 1mw industrial hot water boiler fuel can be divided according to different electric hot water boilers, hot water boiler fuel, gas hot water boiler, coal-fired hot water boiler; pressure can be divided according to whether pressure hot water boiler and two kinds of pressure hot water boiler, we usually call "hot water boiler" refers to the atmospheric pressure hot water boiler, due to its safe operation, people bathing or heating largely adopted this pressure hot water boiler. Type water tube boiler assembly controller computer, all the functions are stored on a smart chip realize intelligent boiler, digital, automatic, user-friendly, intelligent control of boiler water, water reaches the automatic stop heating; screen large font temperature, boiler water temperature at a glance. 2, boiler water temperature can be freely set from 10 deg.] C to 100 deg.] C, the boiler can supply both hot water bath can provide water for drinking, may be a dual oven. 3, the top of the furnace through the air opening is provided, the boiler is in an unpressurised state, there is no danger of explosion, while the machine is equipped with thermal protection (ultra-high-temperature furnace during the heating tube buzzer alarm and automatically stop working, secondary overheat protection (boiler housing temperature exceeds 105 deg.] C, the secondary circuit is automatically cut off), anti-dry water protection (when the furnace is less than the water level is very low, the boiler is stopped and an alarm buzzer) and a number of security. drum such drum type hot water boiler hot water boiler, early mostly modified from a steam boiler made, which in the case of boiler water within a boiler of natural circulation. in order to ensure safe and reliable boiler water cycle, the boiler requires to have a certain height, so these larger boilers, steel consumption, and the cost is relatively increased. However, since this type of boiler capacity and can maintain the natural water cycle, when the system pump is suddenly stopped, the pot can be effectively prevented vaporization of water. it is also for this reason, natural circulating hot water boiler in our rapid development.
