BOILERS FOR PEOPLE THAT KNOW AND CARE®

waste heat boilers to meet your requirements

Rentech manufactures a wide range of watertube and firetube waste heat boilers. These boilers are designed for specific operational challenges such as high flue gas pressures, high solid content, and corrosive gasses; and stringent design standards such as API 936.

  • Flue gas capacities from 50,000 lbs/hr to 1,000,000+ lbs/hr (22,000 kg/hr to 450,000+ kg/hr)
  • Steam capacities from 10,000 lbs/hr to 400,000+ lbs/hr (4,500 kg/hr to 182,000+ kg/hr)
  • Saturated or superheated steam
  • Pressures from 200 to 1,500 PSI (14 bar to 105+ bar )

Our waste heat boilers can be designed with an open bottom to allow for the removal of ash and solids that are byproducts of the flue gas. Additionally, we can design ash hoppers that can be attached to the bottom of the boiler to allow for connection to the customer supplied solid removal system.

Cross Flow WASTE HEAT WaterTube Boilers

Rentech cross flow watertube boilers are a robust design that can be configured to fit into almost any footprint. Tube arrangements can be staggered or inline to maximize heat transfer and minimize draft losses. Rentech’s cross flow boilers are designed with an outer casing thickness to meet the needs of the application. The internal insulation is typically a combination of a refractory insulator and hot face. Rentech is experienced with several types of refractories and can comply with API 936.

Water Wall WASTE HEAT WaterTube Boilers

Rentech’s water cooled waste heat boilers leverage our extensive experience in fired water tube package boilers and integrates that experience into a high temperature waste heat boiler design. Rentech’s water wall boilers are designed with an outer casing thickness to meet the needs of the application. The internal insulation is typically a combination of a refractory insulator and hot face. Rentech is experienced with several types of refractories and can comply with API 936

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.

SULFUR RECOVERY UNITS WASTE HEAT FIRETUBE BOILERS

We manufacture sulfur condensers for use in Claus and SCOT recovery processes.

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.
