PROCEDURE FOR COMPLEX UTILISATION OF MINE METHANE, AIR FLOW, AND HYDROCARBON WASTES OF COAL MINING AND FACILITY FOR IMPLEMENTATION OF THIS PROCEDURE (VERSIONS) Russian patent published in 2010 - IPC E21F7/00 F23K5/00 

FIELD: power engineering.

SUBSTANCE: mine methane in form of conditioned air-methane mixture (AMM) is used in power installation as gas fuel. Not-conditioned AMM is retarded with combustion products with specified upper and lower limits of methane contents. Further the mixture is thinned with air and used as gas fuel. Not-conditioned AMM is thinned with air flow, if contents of methane in it is below the established lower concentration limit. Then it is used for blowing at combustion of hydrocarbon wastes of coal mining and for production of gas synthesis. Produced gas-synthesis is used at combustion of hydrocarbon wastes and/or is utilised as reserve gas fuel for power installation made in kind of a heat generating installation.

EFFECT: rational utilisation of source not-conditioned air-methane mixture (methane 2,5-25%) at its safe transporting via gas lines; also simultaneous-separate utilisation with exhaust air flow in power installations involving hydrocarbon wastes of coal mining both at combustion in power installations and in gasification producing and utilising gas synthesis and methane-air mixture together with air flow as blowing.
