business center gas-fired condensing hot water boilers

State all the more attention to environmental protection, to provide more excellent atmosphere, we respond positively to the country's environmental protection, promote the boiler from coal to gas project. Among the many boiler suppliers, we chose the fast boiler. First, the party quickly done very well in terms of cleaning the boiler, the second is fast side also very comprehensive after-sales involved. The optional gas boiler was used after running fully meet the needs of our pharmaceutical production, both energy-saving and environmental protection, but also a very high thermal efficiency, saved us a lot of fuel costs. --customer feedback

There are two types can designed for gas oil fired boiler.One type is gas oil fired fire tube boiler and another is gas oil fired water tube boiler.Gas oil fired water tube boiler is a packaged boiler with double drums and D-type layout. It has lots of advantages such as sufficient burning, no pollution in the emission, convenient operation, easy installation etc.

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.

Coal fired circulating fluidized bed business center-fired condensing hot water boilers has simple and compact structure, the boiler body consist of combustion equipment, coal feeder, water cooling system, separators, economizers, air pre-heaters, steel frame, escalators, furnace walls and other components, adopt full steel frame.Coal fired circulating fluidized bed hot water boiler from the front to back are arranged in order as combustion chamber separators, tail flue, to ensure good sealing performance, high temperature zone with membrane wall sealing structure, all suspension type, fixed expansion center, dip leg is integrated with the furnace water wall for expansion, improve operating reliability and reduce heat loss, Before furnace is the coal feeder, combustion required air provided by the first and second fan, fuel combustion in the furnace produce flue gas that carrying some fuel, the separator is used to separate flue gas and fuel, the fuel through separation back to the combustion furnace. By adjusting the amount of coal, the primary air and secondary air flow rate and ratio, bed inventory, you can easily adjust temperature inside bed.
