TBWES oil & gas-fired boilers are available in shop-assembled (FM), high-capacity (HCFM), or site-erected (PFM) configurations to meet specific project demands and transport limits.

These boilers are manufactured under license from Babcock & Wilcox, USA. Engineered to deliver high-performance steam and high turndown ratios, they feature D-type construction. Fully water-cooled furnaces and a gas-tight membrane wall design offer high efficiency and low maintenance. Their large-diameter furnace wall tubes and optimised drum internals ensure reliable natural circulation, fast load response, and high steam purity. These boilers are designed for oil, natural gas and other liquid & gaseous fuels.
