Retrofit for small and large boilers include conversion from oil to solid fuels including biomass, waste gases and process waste and process waste.

Water treatment and waste water (sewage/effluent) treatment systems can be augmented and upgraded, avoiding expensive and time consuming investments in additional land and equipment.

Retrofit services are available for
  • Packaged boiler
  • Large boilers
  • Water and waste water treatment systems
  • Air pollution control equipment

Boiler Automation

We provide Furnace draft control system and “Air/Fuel feed control system for solid fuel fired boilers. We also offer Drum level control system.

Product Features
  • Fuel saving of 4-6% by Air : Fuel control
  • Reduction in power consumption up to 40% through furnace draught control
  • Full proof safety against back firing
  • Improved combustion
  • Reduced manual intervention
  • Conventional / PLC based control system available.

Solid fuel conversion

Fuel shift from present oil firing to solid fuel becomes inevitable owing to the raise in fuel cost. With such a vast hike in oil price, the payback turns out to be huge, which compel most of the oil fired boiler users to shift to solid fuel fired options. Fuel conversion is possible with external or integral furnace conversion depending on the space availability in the boiler house.


To recover the heat content from the flue gases of boiler/heater.

Dye Liquor Heat Recovery

To recover heat from dye liquor waste from dyeing application in textile industry. This is normally used to heat water required for the process itself.

Incinerator Exhaust

To recover the heat from incinerator exhaust. This heat can be used to generate steam or hot water or thermal oil heating.

Furnace Exhaust

To recover the heat content from furnace exhaust e.g., activated carbon exhaust. This heat can be used to generate steam or hot water or thermal oil heating.

Engine Exhaust

To recover the heat content from engine exhaust. This heat can be used to generate steam or hot water or thermal oil heating.

We also shall offer cases with external furnace with Membrane panel assembly so that the capacity deration can be ruled out. With this even though initial investment is high, we can offer this with an alternative option of converting the existing SM boiler with above deration by simply putting the external conversion.

Customer can get big advantages like, getting very attractive savings vis-a-vis the investment and also for sutiable cases, it can be recommended for CDM benefits.

Oil & gas conversion

Thermax has complete range of energy efficient burners, covering all aspects of combustion control and monitoring from OILON of Finland, one of world’s leading innovative and customer centric burner manufacturers.

Most of the company’s product development projects today include a major emphasis on emission reduction and automation and OILON now offers customers wide range of ‘intelligent’ low NOx burners.

Our special strength is a wide range of different burners designed to meet varied industrial process heating requirements.

Product range
