Abstract
1. Способ подогрева шахтного вентиляционного воздуха, включающий нагрев атмосферного воздуха дымовыми газами, поступающими из камеры сгорания топлива через выходной газоход и камеру догорания топлива, подачу его в шахту через вентиляционную систему, отличающийся тем, что в поток вентиляционного воздуха, непосредственно во всасывающий канал шахтного вентилятора главного проветривания, дозированно подают присадку горячего воздуха, в камере сгорания используют вторичное дутье, вторичный воздух подогревают в конвективной рубашке боковых стенок камеры сгорания, а в выходном газоходе используют поддув холодного воздуха, который направляют вверх под углом не менее 45°. ! 2. Способ по п.1, отличающийся тем, что в камере сгорания топлива используют комбинированное сжигание топлива. ! 3. Устройство для подогрева шахтного вентиляционного воздуха, содержащее камеру сгорания топлива с боковыми, фронтальной и отбойной стенками и потолочной частью, воздухоподогреватель, воздухораспределительное устройство горячего воздуха, вентилятор горячего воздуха, дымосос, газоходы и воздуховод, отличающееся тем, что камера сгорания топлива снабжена расположенными снаружи вентиляторами вторичного дутья и выполненными в боковых стенках наклонными щелевыми форсунками, которые расположены на высоте 0,8-1 м от поверхности топочного полотна таким образом, что ось потока вторичного воздуха, поступающего из каждой щелевой форсунки, кроме отсечных, направлена в центр отбойной и фронтальной стенок камеры сгорания топлива, а наружная поверхность боковых стенок камеры сгорания топлива снабжена конвективной рубашкой, одновременно являю1. A method of heating mine ventilation air, comprising heating atmospheric air with flue gases coming from a fuel combustion chamber through an exhaust gas duct and a fuel combustion chamber, supplying it to a mine through a ventilation system, characterized in that it enters the ventilation air stream directly into the mine’s suction channel main ventilation fan, dosed to supply hot air additive, secondary blasting is used in the combustion chamber, secondary air is heated in the convection jacket x the walls of the combustion chamber, and in the exhaust duct use blowing of cold air, which is directed upward at an angle of at least 45 °. ! 2. The method according to claim 1, characterized in that in the combustion chamber of the fuel using combined combustion of fuel. ! 3. A device for heating mine ventilation air, comprising a fuel combustion chamber with side, front and baffle walls and a ceiling part, an air heater, a hot air distribution device, a hot air fan, a smoke exhaust, gas ducts and an air duct, characterized in that the fuel combustion chamber is provided with disposed outside by secondary blast fans and inclined slotted nozzles made in the side walls, which are located at a height of 0.8-1 m from the surface of the furnace floor so that the axis of the secondary air flow from each slot nozzle, except the shut-off nozzles, is directed to the center of the baffle and front walls of the fuel combustion chamber, and the outer surface of the side walls of the fuel combustion chamber is equipped with a convective jacket, at the same time
