Operating your boiler with an optimum amount of excess air will minimize heat loss up the stack and improve combustion efficiency. Combustion efficiency is a measure of how effectively the heat content of a fuel is transferred into usable heat. The stack temperature and flue gas Oxygen (or Carbon Dioxide) concentrations are primary indicators of combustion efficiency.

Natural Resources and Office of Energy Efficiency
Typically, reducing O2 in the flue gas by 1 percent- for example, from 5 percent to 4 percent- increases boiler efficiency by about 2.5 percent.

Controlling excess air is the most important tool for managing the energy efficiency and atmospheric emissions of a boiler system.

As graph shows, the effect of air temperature on excess air in the flue gas can be dramatic.


About Us

Welcome to a Clean, Green World, free from Pollution.

Who we are?
We are world leaders in pre-combustion and combustion air trim systems for Solid, Liquid and Gas fuels.

What we do?

Presenting FUEL-CAT & CAT Control System, For the Clean and Green world.

What you get from CAT Control System?
CAT Control System is designed using In-situ Oxygen analyzer and combustion air trimming, which is control by intelligent circuit for maximum optimization of regulating the primary and secondary air by using Variable speed drive of ID/FD fans.

For the benefits of the end users, Dharam Group has tied-up with CANTOR CO2e, a leading global provider to the world’s Carbon Credits and other energy markets.

CANTOR CO2e (cantorco2e.com) is a subsidiary of Cantor Fitzgerald (cantor.com) having 45 billons in assets. It has its headquarters’ in London and San Francisco. It has fourteen offices across Five continents. The company is ranked on top of the CNBC list of low Carbon pioneers. Our other shaholder is Mitsui of Japan (mitsui.com) one of the largest Japanese trading houses.

We and CANTOR CO2e will provide all assistance, consultancy, documentation and help the users of FUEL-CAT to earn Carbon Credits.

Dharam Group has taken a small step towards a big cause.

FUEL-CAT is not just the solution but a movement for a cleaner, greener and better planet, for us and for the future generations.
