The invention provides a low-concentration gas direct combustion utilization intelligent control system. The low-concentration gas direct combustion utilization intelligent control system comprises agas source monitoring and processing system, a main combustion chamber gas supply system, an air auxiliary system, an auxiliary combustion chamber gas supply system, a combustion system and a steam boiler; the gas source monitoring and processing system is externally connected with a gas conveying pipeline; and the main combustion chamber gas supply system comprises a mixing bin and a gas supply pipeline. According to the low-concentration gas direct combustion utilization intelligent control system, the gas concentration and flow are adjusted in real time through expert control according to gas with different concentrations, it is guaranteed that the temperature of a combustion chamber is kept between 800 DEG C and 1200 DEG C, it is guaranteed that low-concentration gas is safely and stably combusted, and tail gas emission reaches the standard; and in the working process of the system, expert control is used for control, various abnormal states can be avoided, and safe and stable operation of the system is achieved.
Description
technical field [0001] The invention relates to the technical field of gas utilization, in particular to an intelligent control system for direct combustion and utilization of low-concentration gas and a use method thereof. Background technique [0002] In the industrial production process of coal mines, high-concentration gas (gas concentration greater than 30%) and ultra-low concentration gas (gas concentration less than 0.75%) can be used directly by relying on existing technologies, avoiding resource waste and environmental pollution. Although low-concentration gas with a concentration range of 9%-30% cannot be used directly, it can also be used to generate electricity by using gas internal combustion engine power generation technology. [0003] At present, the recovery and utilization technology of low-concentration gas with a concentration of less than 0.75% is the countercurrent regenerative exhaust air oxidation technology, and the low-concentration gas with a concen...
