Regarding the issue of waste heat utilization in the riser.
Thread Content
Our factory is planning to adopt waste heat recovery technology for rising pipes. I would like to ask my colleagues in the coking industry: what are the actual performance results, and does it have any impact on production operations?
Our company has successfully developed an efficient heat recovery rising tube for the sensible heat of waste gas from coal coking ovens. After half a year of operation in 7-meter coking ovens, over 19 cycles totaling 621 hours and 39 minutes, including periods of up to 14 days and 18 hours of dry operation, the system was still able to operate steadily at a pressure of 2.0 MPa. It withstood tests at various pressure levels of 3.68, 3.5, 2.5, 2.2, 2.0, 1.8, 1.6, and 0.8 MPa, achieving a gas production rate of 90–100 kg per ton of coke at a pressure of 2.2 MPa. This technology overcomes the problem of high-temperature corrosion materials, eliminates coking, prevents coking in the rising tubes, and makes maintenance easier (only high-pressure air blowing is required). This technology enables high-quality waste heat recovery of the sensible heat in raw gas. During this promotion phase, we welcome the assistance of friends from coking plants to maximize the recovery of the sensible heat in waste gas, thereby achieving mutual energy-saving benefits.

The coking operation remains the same, and the maintenance of the rising tube is simpler – it only requires purging with high-pressure air.
Could I have your contact information? I can come for a technical exchange.
