Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
As shown in fig. 1 to 3, the utility model discloses a radiant heating equipment for marble sheet metal is dried, including horizontal furnace body 1 and the conveyer 2 that the straight line passed furnace body 1, be equipped with radiant heating device 3 on the furnace body 1, radiant heating device 3 includes that the air feed is responsible for 31 and is responsible for a plurality of air feed branch pipes 32 that 31 divide from the air feed, is equipped with solenoid valve 321, blender 322 and combustor 323 in proper order on the air feed branch pipe 32, is equipped with some firearms 324 on the combustor 323, and the top surface of furnace body 1 is all located to combustor 323. The device adopts natural gas as fuel, is distributed into each mixer 322 through the air supply branch pipe 32 to be mixed with air, then is ignited and burnt in the burner 323, and infrared radiation is generated by burning to uniformly heat marble sheets in the furnace body 1. According to the current market cost, the cost of the electric heating method for providing 100kW of heat is 80 yuan, and the cost of natural gas is 39 yuan, so that the gas cost is saved by over 50%, and the equipment is more suitable for popularization in industrial heating occasions.
