Hot blast valve is a valve with the device of hot blast. Hot blast refers to the preheating of air blown into a blast furnace or other metallurgical process. This has the result of considerably reducing the fuel consumed in the process. This was invented and patented for iron furnaces by James Beaumont Neilson in 1828 at Wilsontown Ironworks in Scotland, but was later applied in other contexts, including late bloomeries. Hot blast valve has three basic functions: first, hot blast valves are intended for separation of a hot-air stove from a hot blast main under "on-gas" operation of the former; second, hot blast valves can be used as a shutoff one for separation of a gas burner from the hot-air stove under "on-blast" operation of the latter; third, hot blast and shutoff valves are installed vertically in a pipeline. The pipeline is opened and closed by the movement of the valve disk with the use of electromechanical drive. In event of power failure, it is possible to operate the drive manually. Compared with other kinds of valves, hot blast valve has its own design features. All heat-loaded elements of the valve excluding disk contact surfaces and housing thrust rings are protected with refractory lining. Housing cooling system allows to effectively cool thrusting rings, the most heat-loaded elements of the valve, as well as attachment flanges and housing neck zone providing normal working conditions of flange packings. The valve disk has a solid shell and spiral partitions which form disk cooling system. Cooling water velocity both in the housing and in the disk is above 1 m/sec which ensures removal of mechanical suspensions and eliminates the danger of cooling ducts blockage. Significant reduction of cooling water discharge and maximal protection of heat-loaded elements with refractory lining allow decreasing heat losses. Hot blast valve is applied in large and middle sized hot blast furnace system, working as high temperature hot blast valve, back-draf
