Oil & Gas Fired Boilers

What is Oil & Gas Fired Boilers

A proven water-tube boiler solution for reliable, efficient steam generation using natural gas, refinery fuel gas, LNG, LPG, and liquid fuels. The D-type configuration offers a compact furnace arrangement, excellent combustion control, and high reliability for process industries, refineries, petrochemicals, and power applications.

The boiler features a steam drum, mud/water drum, water-cooled furnace walls, and convection heating surfaces arranged in a characteristic D-shaped configuration. Fuel is fired through specially designed burners to ensure stable combustion and efficient heat transfer, while the convection bank, superheater, and economiser recover additional heat from the flue gases.
