coal-fired water tube hot water boiler Introduction
coal fired boiler is a kind of double-drum longitudinal chain grate stoker steam boiler, it has high thermal efficiency of heating change convection layout, water cycle system is reasonable, water capacity and steam space is large, and has high steam quality. The operating efficiency of the coal fired boiler is stable and has overload operating ability. Light chain belt type assembly grate is matched with stepless speed device, that makes the adjustment method of the best combustion mode to be more complete, the burning light chain grate realizes feed coal by machinery, and it can be equipped with drum and induced draft fan to realize mechanical ventilation. Fuel fall into furnace grate from coal scuttle, is feed in furnace tank along with furnace grate, after the flue gas passing through the behind arch upper chamber, up along the combustion chamber to pass through the smoke chamber and enter into the first tube bundle, then reach the font smoke box, introduced by the induced draft fan to enter into the flue, de-dusting apparatus and chimney, then the smoke is discharged to atmosphere. The coal fired boiler automation level is high, the boiler water supply can be adjusted automatically, high and low level alarm, is equipped with low water level and blowers interlocking protection. The boiler coal, slag discharge operation mechanically, auxiliary engine is complete supporting.
coal-fired water tube hot water boiler Features
1.Furnace and the two sides of burner zone adopts membrane water-cooled furnace structure. The membrane structure of coal fired boiler, our company solely design once used in electric boiler , is now applied in shaped assemble boiler. Its advantages lie in great thermal transmission heat, better heat transfer effect, lower heat loss ,better air impermeability, no wall distortion and no ash leakage.<br> 2.The tubes of water cooling wall go down to the upside of the grate ,which forms the front and back arches. This structure was successfully used in the field-assembled coal fired boiler, with which the heating surface and the overload capacity increased.<br> 3.The frame of front and back arches are made of water cool tubes together with the Roland’s cement mason work. In this way, the phenomena such as arch brick cracking or arch collapsing after long time high-temperature roasting the used three broke lines arch bricks can be avoided, so that the coal fired boiler service life can be extended.
coal-fired water tube hot water boiler Application
We know during the oil processing, the residue from the press consists of a mixture of fibre and nuts in oil plant.Shells are remnants of the oil refining process and have long been abandoned. Until a cement plant in Malaysia uses shells as biofuel, it mixes with coal to produce heat. Today, many European countries, including the United Kingdom, the Netherlands, Italy and other places began to try to put shell mixed coal fuel together to provide energy to alleviate the rising costs of fuel and reduce carbon dioxide emissions.
