The water wall of ZOZEN coal-fired boiler adopts close drainage water wall pipe, which solves the problem that the temperature of the outer surface of the furnace wall is generally higher than the national standard due to the radiation of high temperature flue gas, reduces part of the heat loss and improves the thermal efficiency of the boiler. Reasonable air conditioning device can achieve precise air distribution and improve combustion efficiency. ZOZEN produces coal-fired boilers with a thermal efficiency of over 82%. Many processing plants, chemical plants and other production lines are inseparable from the industrial steam boiler, of which the automatic coal boiler because of the short production cycle, convenient installation and transportation, low input costs by many customers attention to an industrial boiler product.
SZL series boiler is a double barrel longitudinal chain grate boiler, SZL7.0-1.0/115/70-ALL is 10 tons of coal fired hot water boiler, mainly used for heating. The fuel of this type of boiler can be biomass or coal. ZOZEN 10 tons SZL series coal-fired boilers are mainly used for heating and steam production. In addition, they are mainly exported to Southeast Asia, Russia and other regions. Then how to calculate the coal consumption of coal-fired boilers? First of all, 1 ton =0.7MW= 600,000 kcal, then the calorific value required by coal boiler per hour is: 10*60=6 million kcal, the calorific value of 1KG coal is 7000 kcal = 0.7000 kcal, then the coal consumption per hour is 600/0.7=857KG. This value can only be used as a reference, and the exact consumption needs to be calculated according to the actual usage requirements.
The boiler fuel of this series is burned on the grate in the furnace, and the burning flame passes through the low wall to the embers chamber, and from the embers chamber through two flank flue to the front smoke chamber, from the smoke tube bundle to the back smoke chamber, and then is pumped into the atmosphere through the chimney by an induced draft fan. This can make the high temperature tube plate inlet smoke temperature drop, and then auxiliary with backwater ejecting, the bottom of the drum without dead water area, played an effective prevention of tube plate because of supercooling, boiling and scaling and furnace bottom bump, flue gas to smoke chamber can play a role in dust removal, but also reduce the original dust concentration.
ZOZEN is a strong manufacturer of coal-fired boilers. The main models are SZL series double drum longitudinal chain grate boilers, DZL series single drum longitudinal chain grate boilers, SHX series circulating fluidized bed boilers, DHX series circulating fluidized bed boilers, DHL series Angle tube chain grate boilers and SHL series double drum bulk chain grate boilers. High quality boiler products and perfect customer service let us in more than 30 years of production and sales of boilers in the process of the harvest of numerous customers praise.
