摘要:
A heating apparatus includes at least a pair of regenerative burner units (55,55') having a fuel injection nozzle and a heat regenerator provided for a combustion air supply path. One regenerative burner unit (55) is supplied with fuel through a fuel shut-off valve (65) and a fuel change-over valve (63), and supplied with combustion air through a supply and exhaust change-over valve (57) to perform combustion operation. The other regenerative burner unit (55') performs heat regenerating operation by passing a combustion waste gas. Operations of the fuel shut-off valve, the fuel change-over valve and the supply and exhaust change-over valve are controlled depending upon an operation parameter of the heating apparatus.

摘要:
A regenerative burner unit for a heating apparatus comprises a combustion cylinder (3) mounted in a cylindrical housing (15) and having holes (4) in a peripheral wall. The unit includes a main burner (6) having a fuel injection nozzle (7) opening in the vicinity of the rear of the combustion cylinder. A combustion air supply path (13) is provided between the main burner and the cylindrical housing and includes a heat regenerator (14) comprising a plurality of segments (14a,14b,14c).

A heating apparatus includes at least a pair of regenerative burner units (55, 55') having a fuel injection nozzle (7) and a heat regenerator (14, 141, 142) provided with a combustion air supply path. One regenerative burner unit is supplied with fuel through a fuel shut-off valve (65) and a fuel change-over valve (63), and supplied with combustion air through a supply and exhaust change-over valve (57) to perform combustion operation. The other regenerative burner unit performs heat regenerating operation by passing a combustion waste gas. The heat regenerator (141) mounted on the inflow side of the combustion waste gas is made of ceramics and the remaining heat regenerator (142) is made of metal.
