Abstract: Heat radiation from forest fire would cause damage to the equipments in pump stations. Constructing fire-proof barrier around pump station is one of the most effective ways to reduce the fire heat radiation hazard. Rational forest fire-proofsafety distance can ensure the safety of the pump station and save land occupation at the same time. A safety distance calculation model is built based on solid fire radiation model and heat radiation damage code. Taking the Mohe Pump Station as an example, heat radiation flux at different distance from forest fires is calculated by the model, and effects of fire intensity, flame tilt angle and flame temperature on the safety distance from forest fires are analyzed. The safety distance for fire control of Mohe Pump Station is calculated, which provides basis to the determination of safety fire prevention distances for pump stations in forest area.
