Embodiment Construction

[0010] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings. The present invention firstly discloses a method for increasing the power generation capacity of sintering waste heat utilization clusters. The method is as follows: more than two sets of sintering waste heat utilization clusters are connected in parallel to the output main pipe, and the output main pipe is connected to the gas boiler. When any one of the sintering waste heat utilization clusters When the sintering waste heat boiler frequently disassembles due to the shutdown of the sintering system, the gas-fired tube boiler sends steam to the sintering waste heat utilization cluster through the output main pipe. , through the combustion of excess coke oven gas, it not only reduces the environmental pollution that may be caused by excessive discharge of coke oven gas, but also when an abnormal phenomenon occurs in any set of sintering waste...

Abstract

The invention provides a method and device for improving the generating capacity of sintering waste heat utilization clusters. The method comprises the steps that two or more sets of sintering waste heat utilization clusters are connected to a main output pipe in parallel, the main output pipe is connected with a gas-fired boiler, and when frequent splitting, caused by stopping of a sintering system, of a sintering waste heat boiler occurs to any one of the sintering waste heat utilization cluster, steam is conveyed to the sintering waste heat utilization clusters through the main output pipe by means of the gas-fired boiler. The method and the corresponding device thereof have the advantages that energy is saved, consumption is reduced, the environment pollution is small, the service life of equipment is long, and the economic benefits are good.

Description

technical field [0001] The invention relates to the technical field of sintering waste heat utilization for power generation, in particular to a method and a device for increasing the power generation of a sintering waste heat utilization cluster. Background technique [0002] In iron and steel production technology, the energy consumption of the sintering process is relatively high, generally accounting for 10-20% of the energy consumption of the entire enterprise. Therefore, the utilization of waste heat in the waste steam discharged after sintering has become one of the main measures for iron and steel enterprises to save energy and reduce consumption. However, due to the system instability in sintering production, the steam production of high-temperature steam fluctuates, which in turn makes the power generation efficiency of the steam turbine unstable for a long time and cannot meet the design standards. Contents of the invention [0003] The purpose of the present in...
