Anti-freezing measures for coke ovens
Thread Content
During winter snowfall, the snow and ice that accumulate on the slides of the coal loading cars placed on top of the furnace prevent these cars from moving； The high-pressure ammonia pipe has frozen and cannot be used properly. Does anyone have any good suggestions? Thank you.
Mainly from the following aspects: 1. For the main gas pipeline in the basement, ensure that the temperature of the gas is not too low; if necessary, increase the preheated gas temperature appropriately, or insulate the main gas pipeline. 2. Insulate the valves of all pipelines to prevent freezing and cracking. 3. The gas condensate drain pipe must not freeze or get clogged.
Coal loading cars can be connected to furnace gas beneath the slide for ignition and heating, with significant results; (the effect is poor in strong winds)； Using a flexible method of delivering ammonia at specific times and locations during winter for high-pressure ammonia pipelines is a good approach.
How about installing a cover on the slide track to shield it from rain and snow?
This might not work well in the north; with high humidity and low temperatures, freezing will still occur.
The iron stairs should be covered with grass; electrical appliances and wires need to be protected from freezing, snow should be cleared promptly, and the moving parts of equipment must also be protected from freezing.
