Our company has successfully developed a new type of horizontal sleeve hot blast stove with independent intellectual property rights. It involves five disciplines - heat transfer, aerodynamics, combustion technology, welding technology, and materials science. It is a mine specific coal-fired hot blast stove that uses direct brush and secondary circulation methods, divided into manual and machine burning forms. The thermal efficiency can reach 70%. It adopts positive pressure air supply and negative pressure smoke exhaust, and the smoke and air will not mix, especially when the furnace temperature reaches 1000 ℃ -1200 ℃ using "high-temperature heat treatment technology", it will not deform. The supporting electronic control operating system is equipped with an alarm interlock device, which automatically shuts down after an alarm, and will never cause safety accidents, making the DTWRG/DTWRL series hot blast stove of Datong always in a leading position in the industry.

Mechanized combustion hot blast stove: The grate adopts chain grate or reciprocating grate form, realizing grate speed regulation (or electromagnetic speed regulation, frequency conversion speed regulation) to adapt to changes in hot blast stove load and coal type. At the same time, it is equipped with coal feeder and slag remover, realizing automatic coal feeding and slag removal, reducing labor intensity of workers and reducing solid incomplete combustion loss and gas incomplete combustion loss, improving the thermal efficiency of the hot blast stove, achieving the goals of energy conservation, environmental protection, low consumption and high efficiency
