Zozen coal-fired hot water boiler with chain grate Boilers production complete machinery and coal, and is equipped with induced draft fan, air blower for mechanical ventilation, and is equipped with scraper slag machine to complete the automatic slag. The coal fired boiler manufacturing is compact in construction and reasonable in design. It is a kind of horizontal three-return water-fire tube boiler. The boiler is equipped with a bunch of threaded smoke pipe inside the boiler barrel, the left and right sides of the furnace are equipped with light pipe water cooling walls, and the front and rear arches adopt new energy-saving technology.
During the combustion of coal-fired hot water boiler, the fuel falls into the grate from the coal scuttles. After entering the furnace, the flame goes up through the rear arch refraction and turns to the front smoke box after passing through the combustion Chambers on both sides of the body. Then it goes back to the threaded pipe through the front smoke box and enters the energy saving device through the rear smoke box. Finally, it is pumped by the induced draft fan through the flue and discharged to the atmosphere through the chimney.
When a coal fired boiler manufacturing, it is composed of five parts: the boiler body, the smoke duct, the economizer, the dust collector and the pipeline system. Meanwhile, the first four parts have been finished in the factory and transported to the installation site for assembly, which can greatly shorten the installation cycle and ensure the installation quality of products. The type of this series of coal fired boilers is horizontal quick-mounted water-fire tube boiler with natural circulation of working medium. The water circulation is simple, the structure of the pressurized parts is reasonable, under the condition of ensuring the water quality, it can run safely.
During the operation of the coal-fired hot water boiler, the coal with roughly uniform particles is dropped into the coal sill by the active coal loader and then enters the front arch for preheating under the rolling of the chain grate. It burns out in the burning area and falls into the slag pool. The high-temperature flue gas from furnace combustion enters the back of the furnace through the arch mouth at the lower part of the two-wing flue, and then carries out heat transfer through the two-wing flue, flows forward through the front smoke box, enters the convection control and then enters the economizer, dust collector at the end of the pot, and is sent to the chimney through the induced draft fan, and discharged into the atmosphere. The boiler feed water is completed by the boiler feed water pump, the softened water by the feed water economizer, and then into the pot barrel, and then into the left and right header by the drop pipe. On both sides of the water cooling wall heat absorption vaporization occurs steam, steam into the pot steam separator, after separation through the main steam valve into the need for heat flow.
This series of industrial hot water boiler boiler arch is made of fireproof concrete, reasonable structure, compact, low steel consumption, energy saving and environmental protection. The planning function of coal-fired hot water boiler is advanced, and the boiler barrel is made of special steel plate for the boiler. About the container is made of seamless steel tube. The overall design is reasonable, the customer consistent appreciation, use in line with international environmental standards.
Coal fired boiler manufacturing grate with reasonable air distribution, large incineration chamber, coal applicability is strong. Used to all kinds of bituminous coal or anthracite, mixed coal, burning full. Because the high temperature flue gas first into the settlement chamber, and then from both sides into the two wings of the flue, smoke box, so the effect of good smoke removal. Zozen Boilers is committed to producing high quality boiler products, models complete, complete detection means, rich production experience, strong technical team, welcome everybody to come to consult.
