| Combustion Burner | | |
| We hold expertise in offering combustion burners for Boilers & Heaters being used in Coal Power Plants. The innovative design of these burners ensures superior environment is provided for burning fuel including combustion air & removal of the flue gases and ash.
Functioning:
- Coal Pulverisers grind coal to a very fine powder
- Hot air from the Primary Air Fans dry coal in the pulverisers
- This air carries the dry coal powder from pulverisers to the burners in boiler furnace
- In burners coal powder is mixed with required amount of Combustion air & burned in the furnace
Air system:
- The advanced designs of the combustion burner ensure correct amount of air is delivered for combustion
- Use of forced draft fan for supplying of Combustion air
- This fan takes air from atmosphere & blows it into furnace through air ducts

| Heat Recovery Boiler Economizers | | |
| We offer clients heat recovery boiler economizers. These economizers are available in form of finned tube heat exchanger installed in boiler fluid exhaust stack. These are designed to reduce the overall fuel requirements which in turn results in reduced fuel costs & fewer emissions. The offered boiler economizers also help in recovering "waste heat" from boiler's hot stack gas from transferring waste heat to boiler's feed-water. As boiler feed-water is now at higher temperature than when it would have been without boiler economizer, these boilers do not need to provide additional heating to produce steam requirements of a facility or process, thereby using less fuel & reducing fuel expenses.
Process:
- Hot fluid gases pass over finned tubes as boiler feed water circulates inside tubes
- This preheats feed water recovering otherwise wasted heat from escaping fluid gas
- Higher temperature of feed water entering boiler contributes to smoother operation & quicker response to steam demands
Features:
- Boiler economizers help improving boiler's efficiency by extracting heat from fluid gases discharged from final super-heater section of radiant/reheat unit/ evaporative bank of non-reheat boiler
- Heat transferred, again, back to boiler feed-water, which enters at much lower temperature than saturated steam
- Tubing forming heating surface is made from low-carbon steel ensuring non-corrosive atmosphere
Applications:
- Pollution Control
- Engine and Turbine Exhaust
- Ethanol Production
- Petrochemical
- Pulp and Paper
