Method for increasing out-delivered gas per ton of coke

Abstract

The invention relates to the technical field of out-delivered gas per ton of coke and discloses a method for increasing out-delivered gas per ton of coke. The method comprises the following steps of 1) equipment examination, 2) scheme formulation, 3) repair construction, 4) gas volume control and 5) equipment inspection. According to the method for increasing out-delivered gas per ton of coke, professional workers are divided into two groups for detecting setting of coke ovens and meanwhile photographing and recording detected problems; the two group of professional workers perform examination sequentially along the same route to detect potential problems and conclude the detected problems, then professionals formulate corresponding repair schemes one by one for the problems, so that, for oven numbers with serious pore damage, gas leakage can be avoided, and wall surfaces with cracks and corrosion can be plastered to enhance protection over the inside of the coke ovens.

Description

technical field [0001] The invention relates to the technical field of sending coal gas per ton of coke, in particular to a method for improving the sending of coal gas per ton of coke. Background technique [0002] Coke oven gas, also known as coke oven gas, belongs to high calorific value gas, crude gas or raw coal gas due to its many combustible components. A combustible gas produced at the same time as coke and tar products is a by-product of the coking industry. Coke oven gas is a mixture, and its yield and composition vary depending on the quality of coking coal and the coking process conditions. Generally, per ton Dry coal can produce 300-350m3 of coke oven gas (standard state), its main components are hydrogen (55%-60%) and methane (23%-27%), and also contain a small amount of carbon monoxide (5%-8%) , unsaturated hydrocarbons above C2 (2%~4%), carbon dioxide (1.5%~3%), oxygen (0.3%~0.8%)) and nitrogen (3%~7%), of which hydrogen, methane, carbon monoxide and C2 The...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for increasing the gas delivery per ton of coke, which has the advantages of increasing the gas delivery per ton of coke, and solves the situation that the furnace number is seriously damaged by perforation, and cracks and erosions appear on the wall. Cause gas leakage, easy to block the air inlet through the chute and the fire channel of the burner, reduce the thermal efficiency, and increase the self-consumption of gas
