Waste Heat Recovery Boiler

Since as early as 1945, ZBG has devoted itself to develop waste heat boilers backed by proven experience and specialized know-how in boiler manufacture. We have so far delivered as many as over 500 units of waste heat boilers, all of which have won high reputation throughout industries. We will dedicate ourselves to the development of the most sophisticated waste heat boilers to meet various needs in any industrial plant.


At present, annual domestic energy consumption in Japan, for example, amounts to the equivalent to about 400 million kl in heavy oil, most of which are however imported. In the meantime, thermal energy utilization in its industries accounts for 50% only, while the rest of the thermal energy remains unused to be discharged to the atmosphere. ZBG waste heat boilers, or waste heat recovery systems utilize these unused heats effectively in such ways as steam generation, hot water supply, oil & air heating and further power generation, thereby contributing to energy and cost savings.

Cement Kiln Waste Heat Boilers Introduction
Cement kiln heat recovery boiler is a kind of Waste Heat Boiler, with high efficiency and lower consumption, widely applied in cement manufacturing industry, cement plant heat power stations. Cement kiln ash on the tubes of heat recovery boiler affects the heat exchange efficiency. The basic characteristic of cement kiln ash and the deposition on the tubes with different arrangements are presented. Cement kiln heat recovery boilers are manufactured by ZG Boiler which specialized in boiler and pressure vessel more than 70 years. And we have exported cement kiln waste heat boilers to many countries such as India and Venireman. Our cement kiln waste heat boilers have the certification of ISO, CE,GOST and ASME. If you have any question about our cement kiln waste heat boiler, please contact us directly.

Cement kilns Heat Recovery Boilers Parameters
Rated Steam Output: 4~55t/h
Rated Steam Pressure: 0.5~3.82MPa

Advantages of Cement kilns Heat Recovery Boilers
1) Adopted the light tube structure and mechanical vibration method to remove the dust on heating surface and keep the exhaust gas in kiln inlet clean.
2) Used spiral fin tube and low smoke speed structure for the heating surface.
3) All-steel panel structure of cement kiln waste heat boiler to solve the air leakage problem and improve the heat utilization of boiler system.

Three Castoff Mix Burning and Blown Gas Waste Heat Boiler
Waste Heat Boiler for Chemical Industries Introduction
Three Castoff Mix Burning and Blown Gas Waste Heat Boiler widely used in chemical fertilizer plants, chemical plant as the energy-efficient equipment. The three wastes (waste gas; waste water; industrial residue) pollute environment seriously. Waste Heat Boilers have its specialists in energy recycling and efficiently utilization. ZG Boiler offers years of experience utilizing waste gases and recovering its energy in the form of steam. Steam generation is an ideal way to recover waste heat energy from these gases in a form most easily utilized. Our ZG company has developed two types: Vertical Waste Heat Boiler for Chemical Industries and Horizontal Tunnel Kiln Waste Heat Boiler for Chemical Industries. Together with Mixed Fired Boiler for Chemical Industries and Blowing Furnace, waste heat boilers can create plenty of finical and environmental benefits for its owners.
