Waste heat boiler is an equipment that utilizes waste heat from industrial production to generate steam or hot water. In industrial production processes, many processes require the consumption of heat, which is usually discharged into the environment in the form of exhaust gas, wastewater, etc., causing energy waste and environmental pollution. The waste heat boilers is to solve this problem. A waste heat boiler can extract heat energy from waste gas, wastewater, and other heat sources, generating steam or hot water to supply the heat needed in the process. This can fully utilize the waste heat resources in industrial production, save energy, and reduce environmental pollution. In some industrial fields, such as steel, cement, food, textile, etc., waste heat boilers have become essential equipment, which can significantly reduce production costs and environmental burden.

In the textile industry, the heat lost by heat setting machines and sizing machines during the shaping, finishing, and drying of textile products not only wastes energy but also causes environmental pollution. The exhaust gas not only contains a large amount of smoke and dust, but also contains various harmful components such as polystyrene organic compounds and dye additives. It can not only meet environmental requirements but also turn waste into treasure after special processing. Therefore, the waste heat recovery of the heat setting machine has both economic and social benefits. Xinli Boiler's waste heat boiler has also become a standard equipment for more and more printing and dyeing textile enterprises with energy conservation and environmental protection becoming a basic requirement for the textile printing and dyeing industry worldwide. The use of flue gas waste heat recovery boilers can greatly reduce the amount of steam used. Recycling and utilizing this portion of thermal energy can heat water for process production, factory heating, and bathing. Clean water can also be heated to generate steam for use in the production process.

A professional textile production company located in Dhaka, Bangladesh, mainly engaged in sizing processing, fabric weaving and sales, and the production and sales of knitted clothing ordered 2 sets of waste heat recovery boilers from Xinli Boiler. A 1.7 ton and a 3.4 ton waste heat boiler from Xinli Boiler will be used for their production line's waste heat recovery. The picture shows the delivery site of 2 boilers:
