(3), simultaneously, low temperature waste gas produces a certain amount of high temperature combustible exhaust gas dry in putting out process, high temperature combustible exhaust gas comprises 3 kinds, contains the high temperature coke that a small amount of moisture content runs into after burnt upgrading chemical reaction can occur in one, low temperature waste gas, produces some inflammable gass; Also there is the not clean-burning inflammable gas of part in low temperature waste gas itself two; Three, also residual a part of inflammable gas of the high temperature coke after burnt upgrading itself;

(4), high temperature combustible exhaust gas enters into the high temperature combustible exhaust gas admission passage 6383 of centre channel 638 bottoms from the top of high temperature coke quencher 71, entering hole 639 through combustible exhaust gas enters in main internal-quirk 636 and the secondary internal-quirk 6373 of hypomere, the high temperature combustible exhaust gas temperature just having entered is higher generally all at 1000 DEG C～1100 DEG C, but along with waste gas rises and externally does work and dispel the heat in main internal-quirk 636 and the secondary internal-quirk 6373 of hypomere, temperature can reduce;

(5), at this moment give the air that fills in main internal-quirk 636 and the secondary internal-quirk 6373 of hypomere by a blowdown pipe 6321, thereby make high temperature combustible exhaust gas obtain airborne oxygen burning, the amount of the combustible gas in high-temperature combustible gas body is certain after all, and the heat and the temperature that provide coking chamber 61 pyrolysis of coal required are provided;

(6) so, when passing through quirk through the waste gas after tonifying Qi burning, the high temperature combustible exhaust gas of the secondary internal-quirk 6373 of hypomere gangs up hole 6304 around in main internal-quirk 636, mix in main quirk 636 and rise with the waste gas after the high-temperature combustible gas body in main internal-quirk 636 and burning, along with the waste gas after mixed high-temperature combustible gas body and burning can be to providing heat and externally acting to the pyrolysis of coal in coking chamber 61 by ringwall in coking chamber 612 in uphill process, temperature can reduce gradually;

(7) so need to again enter short covering gas by secondary air compensating pipe 6322 in the middle and upper part of main internal-quirk 636, make the waste gas further burning again after mixed high-temperature combustible gas body and burning, this provides required heat and temperature not only to coking chamber 61 pyrolysis of coal, and can make again high-temperature combustible gas body fully burn, improve high-temperature combustible gas work by combustion efficiency;

(8), in addition, owing to having buffer zone 6381 in the middle of main internal-quirk 636 and the secondary internal-quirk 6375 of epimere, ringwall 634 tops in center are provided with perforation buffer zone 6381 and enter hole 6301 with the waste gas of main internal-quirk 636 and the secondary internal-quirk 6375 of epimere, on the quirk partition wall 635 between main internal-quirk 636 and the secondary internal-quirk 6375 of epimere, be provided with waste gas and gang up hole 6303, between the secondary internal-quirk 6375 of each main internal-quirk 636 and epimere, completely mutually connect, waste gas after the burning of tonifying Qi for the second time can be mixed completely mutually, between the secondary internal-quirk 6375 of the main internal-quirk 636 in place and epimere, reaching samming all presses, balanced heat and temperature is provided can to the pyrolysis of coal on whole coking chamber 61 tops,

(9), enter the exhaust air chamber 391 on body of heater 91 tops by the hot waste gas exhaust channel 6306 at main internal-quirk 636 and the secondary internal-quirk of epimere 6375 tops finally by the waste gas after the burning of mistake secondary air compensating.
