double drums coal-fired steam hot water boiler supplies

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.

Learning materials heat boiler 1, the boiler is three safety accessories: water gauge, pressure gauge, safety valve. 2, the normal operation of the boiler water level is 0 ± 40mmH2O, the maximum does not exceed 0 ± 80mmH2O, the normal water pressure of 5.5MPa, to allow the fluctuation range of 4.5-6.0MPa, normal pressure boiler feed water temperature should be 105 degrees Celsius. 3, steam flow is not larger than the normal water boiler feedwater flow reasons, the measuring device instrument to do so. 4, the steam flow rate is less than the abnormal overheating damage reasons of water flow, water wall damage, damage to the economizer, the boiler is full of water, measuring device instrument to do so. 5, points on the furnace process CCP washed three times water gauge, pressures of 0.05-0.1MPa, 1.0MPa, 2.8MPa. 6, it is determined whether the normal water table and put into operation to see if the water level fluctuates slightly exemplar. 7, the boiler water pressure test and the test is divided into P overpressure test of two, when the water pressure P test, the boosting speed of not more than 0.35MPa 0.5MPa down rate does not exceed per minute. To the boiler water blowdown 8, the pressure in the boiler shutdown boiler water temperature drops below 80 degrees Celsius. 9, the position of each ordinary pressure test is hydrophobic doors: a door opening, the second door is closed. 10, the boiler-burner with a swirling-type and DC type two. 11, elemental analysis of coal with a composition: C, H, O, N, S, moisture, ash. 12, the main component of the blast furnace gas is: CO.'S time, nitrogen gas, blast furnace gas pressure is lower than 1500Pa, the user must reduce the amount of gas. Fire stop its pressure 1000Pa, working pressure 4000-8000Pa, the upper limit for the dangerous pressure 10000Pa, the lower limit is 2000Pa. 13, the main component of the coke oven gas: CO, nitrogen gas, coke oven gas pressure is lower than 1500Pa, must reduce the amount of gas, which pressure is 500Pa fire stop, working pressure 5000-7000Pa, the upper limit is 8000 Pa pressure the risk, the lower limit is 1500Pa . 14, the high, the main features of coke oven gas is flammable, explosive, toxic. 15, proximate analysis of coal with a volatile content, fixed carbon, ash and moisture. 16, boiler water circulation loop fault has stagnated, cycling back down the tube vaporization, soft drinks stratification. 17, the pulverized coal burning furnace radiation heat from a heat source of flame, high temperature flue gas convection heat. 18, the pulverized coal ignition and quick combustion conditions are sufficiently high temperature furnace, a sufficient amount of air mixed well, pulverized coal and air. Enough burn time. 19, ignition of pulverized coal into the combustion stage, the combustion stage, burning ember stage. 20, boiler mechanical rolling bearing does not exceed a predetermined temperature 80 degrees Celsius, the slide bearing does not exceed 40 degrees Celsius. 21, with factors affecting the steam load boiler water, boiler water salinity, pressure change, the vapor space of the drum height. 22, the principle of the steam separator drum gravity separation, inertial separation, centrifugal separation, separation of the water film. 23, the first ignition of the pulverized coal volatiles, fixed carbon is the latest ignition, the combustion of carbon is the longest. 24, steam soluble salt contaminated steam quality reasons, mechanical carryover. 25, the normal operation of the boiler drum water level in the glass tube than the water level high 50MM, when the water level in the steam table overall door leak, the water level high water table, the total gate leakage when the water level is low. 26, a method for enhancing heat transfer with a heat transfer coefficient is increased, raising the average temperature difference between the heat transfer, the heat transfer area is increased. 27, into the boiler furnace wall refractory layer, three-layer insulating layer and the sealing layer. 28, light blue flame blast furnace gas, as a bright golden yellow flame co-firing light yellow flame, coal, coke oven gas when the combustion gas as a combustion time. 29, the boiler by the "pot" and "furnace" composition, "pan" refers to a soft drink system is mainly composed of the drum, the downcomer, the header, waterwall, economizer, superheater composition; "oven" refers to a combustion system, a furnace, a burner, an air preheater composition. Calorific value 3.27GJ 30,1 tons of steam.

In a pressurized fluidized bed boiler, the entire fluidized bed combustor is encased inside a large pressure vessel. Burning solid fuels like coal and biomass in a pressurized fluidized bed boiler produces a high-pressure stream of combustion gases. After the combustion gases pass through a hot gas cleanup system, they are fed into a gas turbine to make electricity, and the heat in the hot exhaust gas stream can be recovered to boil water for a steam turbine. Therefore, a pressurized fluidized bed boiler in ZG company has high efficiency and good performance. Each year, ZG invested a lot of money on pressurized fluidized bed combustion technology.
