The chain grate coal-fired steam boiler adopts the membrane water-cooled wall structure on both sides of the furnace chamber and combustion chamber. The advantages of coal-fired boilers are large heat transfer coefficient, good heat conduction, small heat loss, good gas tightness, no deformation of the furnace wall, no ash leakage.
The length of the front and rear shaft of the chain grate steam boiler is longer than that of similar furnaces, which prolongs the burning time of the fuel in the furnace and makes the coal burn fully and reduces the carbon content in the slag. The effective area of the grate is increased, and the overload capacity of the boiler is significantly improved. The air inlet on both sides is adopted, and six independent air chambers are set along the longitudinal direction of the furnace rate. Each air chamber is equipped with independent air regulating device to adjust the air volume of each chamber separately to achieve the ideal combustion regulation effect.
Coal-fired steam boiler is widely used in food industry, chemical industry, packaging industry, pharmaceutical industry, biological equipment industry, washing and ironing, concrete maintenance, cleaning, etc. The main body of this series of steam boilers is a single boiler drum arranged longitudinally. The convection heating surface consists of a threaded flue tube inside the barrel, and the radiant heating surface of the furnace consists of the barrel and water-cooled walls on both sides. Light chain grate is used for the combustion equipment. The whole fast installation form ex-factory. Electrical control to achieve stepless speed regulation, limit parameter alarm and interlock protection.
Coal-fired boilers supply a full range of models, superior quality, over the years the products are sold to more than a hundred countries and regions around the world, won the unanimous praise and trust of users. Zozen Boilers has a perfect sales network, professional and reliable sales team, exquisite manufacturing technology, good after-sales service, to ensure that you can buy the boiler products assured, happy, career full of confidence.
