Conventional fired heat generator with additionally integrated smoke tube pass for waste heat utilization.
Environmentally friendly generation of thermal heat or process heat.through the utilisation of waste heat sources.
High supply reliability thanks to self-firing function.
Robust, reliable and durable.
Versatile design for use with different fuel types and as a multi-fuel firing unit (oil, gas, biogas, hydrogen).
Ideal for combination with combined heat and power units or gas turbines.
Types Of Waste Heat Boiler
Single Drum Waste Heat Firetube Boilers
These boilers remove heat from your flue gas especially when your flue gas pressure is relatively high. We offer one, two, and three-pass designs in both vertical and horizontal arrangements.
Elevated Steam Drum Waste Heat Firetube Boilers
For applications that require high steam production, and steam pressure, we offer waste heat firetube boilers with natural circulation elevated steam drums.
Process Gas Firetube Boilers
Our units can be designed with an internal bypass to ensure the desired process gas exit temperature.
Modular Boilers
For projects with space limitations or shipping constraints, Rentech’s team of engineers can design a modular system that includes large shop-fabricated sections that are quickly and easily assembled in the field.
The problem of secondary reaction heat of smoke and dust
The waste heat boiler flue gas contains volatile sulfides and combustibles, which will further complete the chemical reaction and release heat.The design of the waste heat boiler fully considers the heat of chemical reaction to meet the needs of the production process.
Ash accumulation problem
According to the smoke temperature of each flue, we can reasonably choose the pitch of the membrane wall, control the average wall temperature of the membrane wall, so that the smoke and dust on the convection heating surface will not stick, so as to remove the ash and ensure the ash removal effect of the convection heating surface.
Wear problem
The waste heat boiler has a high dust content, and the wear problem seriously affects the service life of the boiler.Considering the importance of the waste heat boiler, on the one hand, the heating surface pipes are made of thick-walled pipes to improve the strength of the pipes; on the other hand, the flue gas flow rate is reasonably controlled to reduce the wear rate, reduce the failure rate of the waste heat boiler, and improve the service life of the waste heat boiler.
Corrosion problems
Because the flue gas contains SO2, HCl, HF and other acid gases, reasonable selection of boiler steam parameters and control of the temperature point of the heating surface can avoid high temperature corrosion and low temperature corrosion.
