FIELD: burning combustible gas at pressure above atmospheric. ^ SUBSTANCE: proposed plant is used for burning lean gases; it consists of unit for burning gas at pressure above atmospheric including lean gas chamber, combustion chamber, heat regeneration section and exhaust; pipe line supplying lean gas to lean gas chamber; heat removal and pressure equalizing chamber and preheated air chamber; plant is also provided with pipe line supplying the compressed surrounding air to heat removal and pressure equalizing chamber, preheated air pipe line for delivery of preheated air to preheated air chamber; provision is made for hole for delivery of lean gas from lean gas chamber to combustion chamber and hole for delivery of preheated air from preheated air chamber to combustion chamber. Heat removal and pressure equalizing chamber is made for heat exchange between lean gas chamber, preheated air chamber and combustion chamber and compressed surrounding air; lean gas and preheated air are burnt in combustion pressure at pressure above atmospheric. ^ EFFECT: enhanced efficiency; minimum difference in pressure between gas and air chambers. ^ 12 cl, 12 dwg |
