Steam boiler is too many forms, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Say the boiler first the pot. The boiler is a drum boiler with water cooling. Two return pyrotechnic tubes are arranged in the left and right parts of the drum, and the front cigarette box in the front part of the drum is turned back. Between the drum and the bottom box, there is a drop tube and a water-cooled tube, forming the frame of the combustion chamber. There is a steam separator on the top of the drum to reduce the water produced by steam. The heating surface of the boiler is the lower part of the drum, water-cooled pipe and pyrotechnic pipe. The combustion part consists of a chain grate and a drive device, Add the boiler frame on the grate of the composition of the combustion chamber composition. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters, and this kind of boiler has great resistance and needs forced blast. Cinder, discharged from the back of the grate through hawk iron and sent out of the furnace by the slag extractor. From the back of the boiler, the flue gas goes forward from the first return pipe of the boiler, the second return pipe returns to the rear part of the boiler, and then goes into the dust collector to separate the ash, and then through the draught fan, it is discharged from the chimney. The induced draft fan is not only the exhaust gas, but also necessary for the negative pressure operation of the boiler. Steam boiler is pressure capacity Device, safety device is necessary. Essential water level gauges, pressure gauges, safety valves, thermometers, electric pumps that can replenish water under pressure, and steam pumps that can also be used in the event of power outages. Boiler water must be softened and water treatment equipment.

Hot water boiler fuel classified according to different oil 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.

PolockGroup Group was founded in 1999, is a famous comprehensive enterprise in Bangladesh, covering many types of machinery, textile, paper and other production and processing equipment. Whether mechanical manufacturing, textile processing or paper products can not do without the help of steam boilers. High quality steam can not only provide mechanical support for producing power; also meet the textile, paper processing disinfection process needs a number of drying, rinsing and the like. The performance of a steam boiler are very good in general can bring qualitative leap for the production.

So how versatile industrial boilers for energy saving? First, the fuel added through the fuel economizer process various compounds economizer its internal molecular structure will produce changes in the viscosity of the fuel increases the distance between the molecules and the molecules decreases, complete combustion can be performed prior to refining to maximize atomization and so that combustion within the environment can be the most complete combustion, can reduce the heat from the flue more so that the temperature of the flue decreased. Added industrial boiler economizer and may eliminate the tar oil and the combustion secondary coking can be prevented, to prevent incomplete combustion of combustion leaving the furnace wall phenomenon, can achieve high energy saving effect. Second, add condensed industrial boiler economizer section at the time of exhaust of water vapor occurs, they can be utilized with great resistance, they can be fully utilized by the installation of the condensing economizer. Industrial boilers condensing economizer may be mounted through the flue of the boiler, it can effectively recover the energy available in the flue gas, the fuel is reduced defeating by condensation of water vapor in the flue gas absorption compound absorption, reduce pollution emissions have higher environmental awareness. Third, the exhaust heat recovery in high temperature industrial boilers, flue gas containing water vapor has been heat will be in state, not condense into a liquid flows out, part of the flue heat may be collected charged by the waste heat recovery apparatus again use, to maximize the energy use.
