The chain grate boiler is a widely used furnace, accounting for more than 70% of the total number of industrial boilers, and has a history of more than one hundred years. In recent years, with the increasingly stringent environmental protection policies, chain grate boilers have been largely replaced by gas-fired boilers due to low thermal efficiency and substandard emissions. As a boiler manufacturer focusing on technology research and development, Henan Taiguo Boiler Co., Ltd. has improved the performance of the chain grate boiler, optimized the design of a chain grate boiler with high efficiency and low nitrogen emissions, and successfully applied for a national utility model patent. .

The chain grate boiler has mature furnace type, simple operation and management, and easy to master, but it also has significant shortcomings such as incomplete fuel combustion, poor fuel adaptability, and large pollution, which does not meet environmental protection requirements. At present, boiler companies mainly reduce the exhaust gas temperature and excess air coefficient, membrane wall, threaded pipe, stratified feeding and fly ash backburning technology, etc., so that large and medium-sized chain boilers have improved the efficiency during combustion, but combustion pollution Material control technology is still relatively backward, and has not changed the industry as a whole.

In order to solve the above problems, Taiguo Boiler cooperated with Shanghai Jiaotong University to set up a special topic for the research and development of chain grate boilers, with clean combustion technology as the starting point, through the combustion test of various fuels, the establishment of mathematical models, and scientific layout based on the test results Furnace arch, furnace wall, furnace heating surface and secondary air improve boiler combustion efficiency while reducing the initial emission of nitrogen oxides, sulfur dioxide and other pollutants.
