The specific embodiment
As shown in Figure 1, a kind of high speed multiple spot pulsed heating by electric cooker device, by burner (1), build plate (2), heat exchanger I (4), heat exchanger II (6) and flame distributor (12) and form.
One end of burner (1) is inserted and is built in plate (2), middle part is communicated with heat exchanger I (4) by air inlet I (3), the other end is communicated with heat exchanger II (6) by air inlet II (5), and the discharge flue of heat exchanger I (4) and heat exchanger II (6) is communicated with by pipeline I (7).
As shown in Figure 3, in heat exchanger I (4), be provided with heat exchanger tube I (17), heat exchanger tube I (17) one end communicates with the smoke exhaust pipe I (10) through building plate (2) by long-pending smoke-box I (18), and the other end is communicated with pipeline I (7) by smoke evacuation chamber I (19).Air blast (9) is connected with heat exchanger I (4).
As shown in Figure 4, be provided with heat exchanger tube II (20) in heat exchanger II (6), heat exchanger tube II (20) one end is communicated with pipeline I (7) by long-pending smoke-box II (21), and the other end communicates with chimney (11) by smoke evacuation chamber II (22).
Combustion air carrier pipe (16) is communicated with the air heat-exchange chamber II (24) in the air heat-exchange chamber I (23) in heat exchanger I (4) and heat exchanger II (6).
Insert in burner (1) one end of nozzle (8), and the other end in use, is connected with the waste combustible coal gas of steel mill.The degree of depth that nozzle (8) inserts in burner (1) will be over the position of air inlet I (3).
