Through years of understanding and feedback from existing users, continuously learning from experience, and innovating and improving the design, manufacturing, and installation processes, the carbon kiln waste heat boiler fully adapts to the requirements of large fluctuations in waste heat flue gas and safe and stable operation of customers. At present, the carbon kiln waste heat boiler operated online by Zhengguo has an evaporation capacity of 3t/h to 50t/h, and has formed a series of carbon rotary kiln waste heat recovery boiler products, which have been widely praised by users.

Compared with the traditional carbon kiln waste heat boiler, Zhengguo carbon kiln waste heat flue gas boiler occupies a small area and saves investment; Novel structure and superior performance. The dusty flue gas is discharged outside the furnace after passing through the slag condenser, superheater, convection tube bundle, and steel tube economizer. The boiler slag pipe is formed by thinning the front water-cooled wall. The superheater is a horizontally suspended structure, divided into a high temperature section and a low temperature section, with an intermediate cooling arrangement; The convective tube bundle is arranged in a straight row, with the flue gas flowing through the middle of the two baffles to increase the velocity of the flue gas and form a transverse scour, thereby improving the heat transfer capacity of the convective tube bundle; The economizer adopts a boiler serpentine tube with horizontally flushed staggered arrangement; The middle part of the water cooling system is a membrane water-cooled wall partition, which not only increases the heating surface, but also improves the sealing and safety. The front and rear water-cooled walls also use membrane water-cooled walls.
