Described bottom flue horizontal subdivision wall is from top to bottom arranged in ladder along the corresponding little partition wall place of regenerator of gas inflow direction, arranges with bottom flue horizontal subdivision wall interval, layer both sides.
Described bottom flue horizontal subdivision wall is connected with the little partition wall of regenerator by the little partition wall of bottom flue at corresponding regenerator little partition wall place, forms gas buffer chamber in its junction by bottom flue lining brick, the little partition wall/regenerator of bottom flue little partition wall/heating system center partition, bottom flue horizontal subdivision wall/bottom flue shop fixtures brick.
Described setting device is manual regulation flap valve or self-acting valve plate valve.
Compared with prior art, the beneficial effects of the utility model are:
1) by being separated to form multiple gas passage to bottom flue, and then realizing carrying out accurate tolerance flow-dividing control to the low-grade gas/air of heating coke-oven in outside, improve combustion chamber length to the homogeneity of temperature distribution and accuracy;
2) automatic control can be realized, improve operating environment, reduce labor intensity, increase work efficiency and security;
3) gas flow of the little lattice of each regenerator can be entered by fine adjustment, improve energy utilization rate, energy-saving and cost-reducing.
