Thermax, headquartered in Pune, India (160km from Mumbai), offers products, systems and solutions in energy and environment engineering to establishments around the world. Its business expertise covers heating, cooling, waste heat recovery, captive power, water treatment and recycling, air pollution control, and performance chemicals.
The Boiler & Heater Group, Thermax’s largest business division, provides equipment and solutions for generating steam and power as well as fired heaters for various applications. The Group’s services arm provides renovation and modernisation (R&M) solutions for old boilers and heaters.
Among the products offered by The Boiler & Heater Group are AFBC boilers, CFB boilers, waste heat recovery boilers, exhaust gas boilers, heat recovery steam generators (HRSG), and fired heaters.
The Group’s engineering office is equipped to undertake process and detailed engineering of boilers and fired heaters across a wide range of capacities and pressure / temperature ratings. Equipment can be designed and supplied, depending on customer preference, either in fully assembled condition or shipped loose to project site. The engineering office has access to the manuals, databases and engineering practices of Thermax’s technical collaborator, Babcock & Wilcox Power Generation (USA), as well as their latest software programs.
In addition, Thermax offers accessible and friendly after-sales support and a convenient spare parts service. The company’s international sales and service network covers South East Asia, the Middle East, Africa, Russia, the UK and the US. It is fully accredited to ISO9001 : 2000 and ISO 14000.
Atmospheric fluidised bed combustion boilers - AFBC boilers
Atmospheric fluidised-bed combustion (AFBC) boilers offer efficient, cost effective and reliable steam generation. AFBC technology promises to provide a viable alternative to conventional coal-fired and other solid fuel-fired boilers.
Thermax utilises the technology of Babcock & Wilcox to offer hopper bottom design AFBC boilers with a capacity of up to 300t/hr of steam generation. These AFBC boilers are designed with no moving parts in the combustor, which ensures reduced maintenance costs. Uniform temperature distribution in the bed along with the agitating characteristic of the fluid bed provide optimum combustion, resulting in a minimum of unburnt fuel, reduced carbon monoxide emissions and improved efficiency.
Circulating fluidised bed boilers – CFB boilers
Circulating fluidized-bed (CFB) boiler technology offers high reliability and availability coupled with low maintenance costs, and complies with stringent emission regulations. The CFB technology utilised employs a unique, simple U-beam particle separator design. This CFB technology helps you to:
- Avoid costly maintenance and outages caused by thick refractory failures as seen in CFB boilers with hot cyclone design
- Reduce the erosion potential compared to hot cyclone design
- Avoid sootblower-induced erosion
- Reduce maintenance costs compared to mechanical / pneumatic systems
Thermax CFB boilers are capable of burning a wide range of fuels allowing for less expensive fuel preparation and thus a reduction in costs. The solid fuel-fired CFB boilers use internal recirculation with two-stage solid separation system in capacities up to 680t/hr.
Heat recovery steam generator – HRSG
HRSGs from Thermax are also based on technology from Babcock & Wilcox. Thermax HRSGs incorporate the latest advances in thermal technology, offering such benefits as multiple pressure levels and unprecedented reliability.
Thermax can design and supply HRSGs for gas turbines ranging from 5MW to 320MW, with steam generation capacity up to 500t/hr.
Waste heat recovery boilers
Thermax’s waste heat recovery boilers meet the twin objectives of cooling process gases and recovering useful heat to produce medium and high-pressure steam for meeting process steam and/or captive electric power requirements. Several industrial processes give off useful heat, which is normally carried away by the emitted gases. Recovering this heat helps improve the overall economics of the industrial process. Investment in a boiler can often be recovered within 6 – 24 months.
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 when necessary. Waste heat recovery boilers can be customised to meet a large range of process requirements.
Thermax offers single drum and bi-drum type boilers in the biomass fired boilers category. The boiler is a ‘travelling grate’ type, wherein the grate is driven by hydraulic drives. In special applications even pinhole grates can be provided. Thermax can supply and design travelling grate boilers with steam generation capacity upto 180t/hr.
Renovation and modernisation solutions – R&M
Renovation and modernisation (R&M) solutions offered by the Boiler & Heater Group address concerns like inefficient operation, frequent breakdowns and reduced availability of boilers and heaters due to ageing of the equipment. Among the services provided are the following:
- Condition assessment, residual life analysis and engineering studies
- Fuel conversions and firing system upgrades
- Utility boiler revamps
- Performance enhancement solutions
- Pressure part replacements and upgrades
