Unsteady-state feedforward adjusting method for low-NOx coke oven heating gas, and coke oven

Abstract

The invention provides an unsteady-state feedforward adjusting method for low-NOx coke oven heating gas, and a coke oven. The coke oven comprises a plurality of coking units. Each coking unit comprises a carbonization chamber, a combustion chamber, a regenerative chamber, a gas regenerative reactor, an air regenerative reactor and a reversing valve, wherein the carbonization chamber and the combustion chamber are arranged at an interva; the regenerative chamber is divided into a gas regenerative chamber and an air regenerative chamber; each vertical flame path of the combustion chamber is respectively connected with the gas regenerative chamber and the air regenerative chamber; a gas regenerative chamber flue communicates with the upper part of the gas regenerative reactor; an air regenerative chamber flue communicates with the upper part of the air regenerative reactor; the lower portion of the gas regenerative reactor communicates with a gas pipeline and a gas flue; the lower portionof the air regenerative reactor communicates with an air pipeline and a flue; and an ammonia pipeline is connected with the upper portions of the gas regenerative reactor and the air regenerative reactor. The coke oven can reduce the energy consumption of coking and the NOx content of flue gas and improve the production efficiency of coking, is prolonged in service life, and meets the requirements for efficient, energy-saving and environment-friendly coking production.

Description

technical field [0001] The invention relates to coking production technology, in particular to an unsteady, low NO x Coke oven heating gas feed-forward adjustment method and coke oven. Background technique [0002] The coke oven is composed of process equipment and furnace body. The coke oven body includes refractory masonry such as carbonization chambers, combustion chambers, and regenerators; process equipment includes gas heating systems, furnace equipment, and gas collection systems; a coke oven consists of approximately 110 to 130 carbonization chambers. The carbonization chamber and the combustion chamber are arranged at intervals along the longitudinal direction of the coke oven. The combustion chamber of the coke oven is composed of 15-20 sets of standing fire channels. The heat generated by the combustion of gas in the vertical fire channels supplies heat to the coal in the carbonization chamber on both sides through the combustion chamber walls. The temperature o...
