Thermax - AFBC and CFBC Boilers, Exhaust Gas and Waste Heat Recovery Boilers, Fired Heaters and Heat Recovery Steam Generators

Thermax is a leading provider of sustainable and integrated solutions in energy and environment areas of power and other core sectors globally. Headquartered in Pune, 160km from Mumbai, India, Thermax manufactures a wide range of steam generation equipment such as AFBC boilers, CFBC boilers, fired heaters, waste heat recovery boilers systems, exhaust gas boiler and heat recovery steam generators (HRSG) of capacity up to 500t/hr with superior value to facilitate efficient operation of plants

AFBC BOILERS

The fluidized bed combustion is generally developed in atmospheric fluidized bed combustion (AFBC) boilers and circulating fluidised bed combustion (CFBC) boilers. The AFBC boilers technology is an ideal alternative to conventional coal-fired and other solid fuel-fired boilers for industrial applications.

Thermax offers hopper bottom design AFBC boilers with capacity up to 300t/hr of steam generation. Thermax uses the technology of Babcock & Wilcox, USA, in its AFBC boilers.

The AFBC boilers reduce the maintenance cost, as there are no moving parts in the combustor. Uniform temperature distribution in the bed is ensured and the agitating characteristic of the fluid bed provides optimum combustion.

CFBC BOILERS

CFBC boilers are designed for high reliability and superior performance. The CFBC boilers comply with stringent emissions regulations at a low maintenance cost. This CFBC boilers technology is unique and includes a simple U-beam particle separator design.

The CFBC boilers are suitable to burn a wide range of fuels and will reduce fuel cost. Fuels burned in B&W CFBC boilers are high ash-waste coal, high sulphur coal, lignite, pet, coke, anthracite clum, wood paste, etc. The solid fuel-fired CFBC boilers use internal recirculation with two-stage solid separation system in capacities up to 120MW.

PROCESS INTEGRATED WASTE HEAT RECOVERY BOILERS

The waste heat recovery boilers meet the twin objective of cooling process gases and recovering the useful heat from them to produce medium and high-pressure steam for utility purposes. Several processes give out useful heat, which is normally carried away by the emitted gases. Recovering this heat through a process integrated waste heat recovery boiler is economical.

The process integrated waste heat recovery boilers are available in water tube or fire tube versions to suit individual process requirements. Additionally an option for auxiliary firing can be provided with the waste heat recovery boilers when necessary. The waste heat recovery boilers are customised to meet a large range of process requirements. The waste heat recovery boilers produced by Thermax are extensively used in the power industry.

FIRED HEATERS

Boiler & Heater group of Thermax offers fired heaters for a wide range of applications in refineries, petrochemicals, fertilisers and chemicals. The fired heaters are used in customised charge heaters, crackers, vaporisers, super-heaters, start up heaters and reformers.

Thermax designs fired heaters for high operating efficiency of more than 90%. The international standard fired heaters produced by the company handle a variety of fuels and can be customised as per customer specifications.

EXHAUST GAS BOILER

The exhaust gas boiler (EGB) recovers the heat from the fuel gas of diesel gensets to generate steam / hot water or useful heat for process heating / cooling. Depending on system design, the exhaust gas boiler can enhance the efficiency of a DG set based system by up to 20%. The exhaust gas boiler leads to reduced overall process costs. The exhaust gas boiler is available in various configurations. Some of them are: single drum re-circulation exhaust gas boiler type, smoke tube exhaust gas boiler type, two drum or single drum natural circulation water tube exhaust gas boiler type, etc.

HEAT RECOVERY STEAM GENERATOR

Thermax HRSG is based on the technology from Babcock & Wilcox of USA, who have installed over 100 HRSG worldwide. These HRSG incorporate the latest advances in thermal technology offering such benefits as multiple pressure levels and reliability. TBW can design and supply HRSG behind gas turbines ranging from 5MW to 250MW, with steam parameters up to 500t/hr, pressures up to 135kg/cm²g and 5,400°C temperature.
