Chenkai: The Extra-large flue gas heat exchanger has been successfully delivered! Help Xinjiang Qiya Aluminum and Electricity achieve green upgrading

Recently, the super-large flue gas heat exchanger independently developed by Chenkai International Trade Co., Ltd. was officially launched and set off for the site of the ultra-low emission renovation project of the calcination furnace flue gas of a certain aluminum and electricity company in Sweden! This "giant" (approximately 10.4 meters in length, 3.3 meters in width, 7.4 meters in height, and weighing 51.3 tons) will shoulder the dual mission of recovering waste heat from high-temperature flue gas and protecting the system, providing customers with a one-stop solution for energy conservation and consumption reduction, ultra-low emissions, and cost optimization.

Technological breakthroughs · Hardcore strength

The aluminum power raw material dryer has seen a decline in efficiency and an increase in maintenance costs due to long-term operation, and urgently needs to be upgraded and renovated. The international technical team of Chenkai innovatively proposed a "in-situ replacement + thermal energy reuse" solution - utilizing half of the shell space of the original dryer to precisely arrange the new heat exchanger, achieving dual optimization of space and efficiency.

The aluminum-power project is another benchmark case of Chenkai International's green transformation in high-energy-consuming industries. Through customized design, we not only addressed the pain points of the customer's original equipment, but also created long-term economic benefits for them through the heat energy recovery system

Core advantage

High-temperature tolerance: Stably processes flue gas above 400℃, efficiently cools it down to below 160℃, ensuring the safe operation of subsequent dust removal, desulfurization, denitrification and other equipment.

✅ Waste heat into benefits: The huge amount of recovered waste heat can preheat process air, heat boiler feed water or provide heating, directly reducing fuel consumption by more than 15%.

✅ Long-term protection: Prevent damage to system equipment caused by over-temperature, extend service life, and the annual maintenance cost is expected to be reduced by 30%;

✅ Low-carbon empowerment: Annual carbon dioxide reduction can reach several thousand tons, helping customers achieve their environmental protection goals.
