Coal-Fired and Thermal Power Plant EPC — 25 MW to 300 MW
Circulating fluidised bed technology for local coals, low-grade fuels and applications where fuel flexibility matters more than headline efficiency.
Coal-fired capacity is contracting in many markets, but it remains the backbone of base-load supply across South and Southeast Asia, and it is still being built where domestic coal is the cheapest available resource. Our work in this segment is concentrated on industrial captive plants and utility units up to 300 MW.
CFB boilers are our default for local coals with high ash, high sulphur or variable quality, because they tolerate fuel variation that would force a pulverised coal unit into derating. Where emission limits tighten, we integrate SNCR or SCR and electrostatic precipitation from the design stage rather than retrofitting later.
Where this plant type fits
- Utility base-load units — 25–300 MW units for grids with domestic coal supply.
- Industrial captive plants — Captive coal or lignite plants for cement, paper, textile clusters and industrial parks.
- Low-grade fuel utilisation — Lignite, high-ash coal, coal washery rejects and petcoke blends.
- Repowering and efficiency upgrades — Boiler and turbine replacement on ageing units.

Frequently asked questions
Answers to the questions we are asked most often on this subject. If yours is not here, ask us directly.
Why choose CFB rather than pulverised coal?
CFB tolerates wider fuel quality variation, burns lower-grade fuels without derating, and achieves lower NOx formation in the furnace. The trade-offs are slightly lower efficiency at large scale and higher auxiliary power. Below 150 MW with variable fuel, CFB is usually the better choice.
Can the plant meet current emission standards?
Yes, with the right equipment from the start. We design to the local standard, and where that standard is likely to tighten we recommend designing to the stricter figure upfront — retrofitting FGD or SCR into an operating plant costs two to three times more than including it in the original build.
Is coal still viable for new capacity?
In markets with domestic coal and no carbon pricing, yes, particularly for captive industrial plants. Where carbon pricing or financing restrictions apply, we recommend evaluating biomass co-firing or a gas-based alternative in parallel — we will say so directly if the coal option does not stand up financially.
