A coal mine in Shanxi uses high-temperature hot air from gas oxidation to produce saturated steam, supplying heated air to wellheads to prevent freezing.

Total gas processed: 2,100 Nm³/h of pure methane.

Steam output: 20 t/h.

Phase I: Covers 350 m², processes 420 Nm³/h of pure methane, and generates 4 t/h of steam.

Annual savings during the heating season: At least 1.2096 million cubic meters of natural gas.

CO₂emission reduction: 16,300 tons per heating season (120-day heating period).

Project timeline: From equipment installation to commissioning completion, completed in just 20 days.

Location: Guizhou Province

Installed Capacity: Upgrading of 18 units of low-concentration coalbed methane gas gensets Commissioning 

Period: Upgrades completed progressively from February to October 2021
