Frequently Asked Questions (FAQ) about Solid Fuel Fired Steam Boiler

A hybrid boiler combines a water-tube furnace with a smoke-tube shell. This design allows for a larger furnace volume, which is essential for the efficient combustion of bulky solid fuels like wood or husks, while the smoke tubes provide excellent heat transfer to the water.

While it is designed for multi-fuel flexibility, it is best to calibrate the grate and air-flow for the primary fuel being used. However, it can easily transition between different biomass types (like briquettes to pellets) with minor adjustments.

The standard CP-F series is designed for pressures ranging from 10.54 Kg/cm² to 21 Kg/cm², making it suitable for high-pressure industrial applications that require high-temperature saturated steam.

The boiler features a strategically designed grate system (stationary or moving, based on capacity) that allows for easy ash collection and removal, ensuring the furnace remains clean for optimal heat transfer.

Yes. Given the capacity (up to 10 TPH) and pressure (up to 21 Kg/cm²), the COMBIPOWER-CPD is manufactured and certified according to Indian Boiler Regulations (IBR) to ensure maximum safety.
