A SYSTEM FOR STABILISING COKE-OVEN GAS PRESSURE DURING PAUSE TIME BETWEEN REVERSALS

摘要

The use of the invention: in the field of coke and by-product process for stabilising pressure in a supply network of a heating system of coke-oven batteries during pause time between reversals in coke-oven batteries. The essence of the invention: the system for stabilising coke-oven gas pressure in its network during pause time between reversals in coke-oven batteries, which comprises a coke-oven gas line with stop valves installed therein, the gas line being linked to a turbo blower station. At least one gasholder is connected to the coke-oven gas line by a supply gas pipeline equipped with a shutoff valve and a pressure gauge and configured to temporarily accumulate an excessive volume of the coke-oven gas and then to feed it into the plant gas network via a bypass line of the fuel gas pipeline, wherein the coke-oven gas pipeline is equipped with shutoff valves and connected to the turbo blower station via said bypass line. The gasholder is designed as a variable volume flexible reservoir made of a rubberised fabric. The turbo blower station comprises at least one blower with a gas pipeline and stop valves. The technical result: the stabilised pressure in the gas pipeline; the rational use of the fuel gas; elimination of gas emissions in the atmosphere during reversals of coke-oven batteries; and provision of the operational reliability and stability to the system in general.
