Thermal Efficiency
Engineered with advanced multi-fuel combustion systems, capable of efficiently burning a wide variety of Coal -based fuels to maximise operational efficiency using locally available, cost-effective renewable resources.
Domestically sourced coal with variable GCV (3,000–4,500 kCal/kg); cost-effective primary fuel for continuous thermic fluid heating with stationary or bubbling bed grate systems
High-GCV imported coal from Indonesia, South Africa, and Australia (5,000–6,500 kCal/kg); superior thermal performance for high-capacity, high-efficiency thermic fluid applications
Low-rank lignite with high moisture content (2,500–3,500 kCal/kg); optimised with dedicated bubbling bed combustion technology for full energy extraction
Sub-standard and washery reject coal grades (2,000–3,200 kCal/kg); utilised with advanced grate systems for maximum heat recovery from otherwise waste fuel streams
Blended coal strategy combining Indian and imported coal grades; optimises fuel cost while maintaining consistent GCV input and stable thermic fluid outlet temperature
Combustion System Options |
1. Stationary Grate — Ideal for sized coal, larger lumps, and medium-GCV coal grades requiring extended burn time on a fixed bed |
2. Bubbling Bed — Advanced fluidised bed technology for mixed coal grades, variable moisture content, and low-GCV coals for consistent combustion |
3 Fluidized cum Bubbling — Advanced combined fluidised and bubbling bed technology for mixed coal and biomass co-firing — maximum fuel flexibility for variable fuel availability scenarios |
