The DEN Bima Sakti – 40 Stoker Boiler is available in a wide range of capacities and a variety of fuel options such as for a coal power station or a biomass power station. The boiler was designed by DEN’s own expert engineering team to answer the demand from state utility operators and private industry players for reliable, and energy efficient power generation while offering flexible and tailored solutions to each client.

The DEN Bima Sakti – 40 boiler offers a number of unique features which significantly improve the boiler’s efficiency and reduce harmful emissions. The expertly crafted over fire air system is made up of strategically located high pressure air jets above the fuel bed to create turbulence and interrupt the stratification of combustible gases above the furnace as well as providing more force for thorough mixing of the fuel particles thus ensuring a complete gas combustion process.

The travelling grate provides a continuous ash discharge system with air cooled grates and when combined with the over fire turbulence system, it results in rapid combustion of fine fuel particles. The fuel feeder device and mechanical spreader respond quickly to changes in steam demand while the separation system removes fly ash from carbon before it is re-injected into the high temperature zone of the furnace for improved combustion efficiency.

The innovative design allows for a range of fuel sources with the ability to utilise all known solid fuel types in a clean and environmentally sustainable manner including coal as well as wood chips and rice husks which would otherwise go to waste. With its streamlined combustion system, such fuels can also be burned simultaneously providing greater flexibility and low operational costs.

Boilers can be customised in terms of capacity with steam flow from 10,000 kg/hour up to 200,000, design pressure from 15 kg/cm2G to 125 kg/cm2G and design temperature from saturated to 540 °C.
