Title:
LOW-CONCENTRATION GAS DIFFERENTIAL COMBUSTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/012417
Kind Code:
A1
Abstract:
Disclosed is a low-concentration gas differential combustion device. From a combustion perspective, continuous combustion of differential units is respectively carried out in a longitudinal direction and a transverse direction, such that the problems of a sharp rise in pressure, and detonation and explosion due to gas accumulation when gas within the explosion limit is ignited are eliminated. The low-concentration gas differential combustion device comprises a low-concentration gas super-cooling dehydration and demisting device (10), a gas pre-treatment device (20), a combustor, a long-term burning device, a high-energy self-heat dispersing rapid ignition device, a combustion chamber (60) and a waste heat utilization device. With the low-concentration gas differential combustion device, the problems of gas escaping, forced direct emissions, low heat efficiency, concentration over-limit explosions, increased equipment volume and increased investment in the reversal process of the existing exhaust air oxidation technology, and the problems of a narrow gas adaptation concentration range, a low adaptive concentration and pressure change amplitude, a poor combustion temperature adjustability, a high NOx content, a high shutdown rate and a low gas utilization rate in the low-concentration gas internal combustion engine power generation technology are solved.
