Three Pass Structure Oil Gas Fired Hot Water Boiler

6 tons gas steam boiler steam pressure adjusting a boiler operation, must frequently monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. Second, increasing boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. Third, the boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and the amount of feed water 8 to adjust. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes.

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.

What are the advantages of the three pass structure oil fired hot water boiler often a little later sure understanding of the principles and methods of using hot water boiler, Henan so fast boiler editor here is also not introduced because a little later thirty-two. If only the gas hot water boiler favorite words, web editor can explain a little later period of his merits, the following look at what advantages it fired hot water boiler in the use of step. Simple: bank up a fire, ash, add water, thanks to ignition this step, Fenghuo is the first time the ash, the ash cleared clean, then covered in coal bucket full of coal door only. Environmental protection services gas hot water boiler is sure to meet the economic and social development, and therefore, gas hot water boiler full of hospitality by everybody, and its requirements are very large, the advantages of gas hot water boiler itself Del it changes the space Philippine law is enormous.

Simple, fast and easy maintenance: the use of fixed-frequency automatic feeding, wind ash, simple operation, small amount of work, only single person on duty, biomass burner stove is a lot of companies the most appropriate. The fuel to the original wide: this burner to wood, wood pellets as a raw material, high calorific value, straw particles and avoids coking caused due to facilitate the situation. Heat is very high: the ability to quickly raise the temperature, but there is no dust, not to mention there is no cause smoke, like that of the nearby environment made it difficult to cause any damage. Application of Gas hot water boiler is very simple, he has a very unusual design, is so unique design can have a decorative role, but also there are gas hot water boiler structure is all very unusual . Hot water boiler obvious effects of eco-friendly low-carbon eco-environmental effects of environmental hot water boiler obvious: the secondary energy source is biomass fuel, maintain ecological use of renewable energy. High temperature press section ignition step, dust is low NOX, SO2, dust and sewage treatment, is gasoline and diesel (gas) burner, electrical heating etc. The most suitable alternative. Tar smoking, waste water and other waste water treatment: pyrolysis using pilot step, tobacco tar, or the like to immediately ignite a gaseous method, solving the high tar content of the biomass gasification bottleneck, avoiding hand caused by tobacco tar Water pollution gases. Heating temperature is increased: with the wind again using step, the furnace pressure in the jet region 500-700mm water column to ensure all of the normal stream. Continuously feeding the continuous production of flame stability, high temperature section temperature exceeds 1300 ℃, is added to industrial applications. Thus says the advantages of hot water boilers are very much hope that a little later steps in the application can make use of features to get plenty of shape.
