Our first combustion system dates back to the 1950''s and had a 2 megawatt watercooled inclined grate for biomass firing. Thanks to our experience with inhouse water circulation, the combustion system was integrated into the boiler''s natural circulation to achieve optimal cooling of all components exposed to high temperatures.
Jul 22, 2015 · All these types can burn biomass fuel, although CFB boilers are more commonly used for coal. BFB and CFB boilers have the highest thermal efficiencies since they A popular travelling grate is the aircooled vibrating grate. Fixed grates are an older design that have to be manually deashed. The other technologies have automatic ash removal.

With the techniques based on grates (such as inclined grate, traveling grate, chain grate and vibrating grate), the fuel is usually fed automatically onto the grate by gravity. As the fuel bed moves, moisture is driven off initially, followed by ignition, burning and finally cooling when the ash is removed.
Fibrous fuels are best burned on steamjet cleaned stationary grates. Air or water cooled vibrating grates can be used to burn fibrous fuels with a high ash content. On a spreader stoker, coal is thrown largely to the rear of the furnace from where it travels, whilst burning, to

limit applies to the vibrating grate stokers. Since so many of the component systems which make up the watercooledand aircooled vibrating grate stokers have sub stantial track records of their own, the machine cannot be considered revolutionary. The vibrating grate stoker firing system has evolved as a response to the need for a machine
Since biomass consists of "recently alive" material, burning biomass is CO 2neutral in the sense that it only releases the quantity of CO 2 that the plant absorbed during growth. Some biomass needs pretreatment before the fuel is fed onto a combustion grate where it is burned.
As a renewable and environmentally friendly energy source, biomass (ie, any organic nonfossil fuel) and its utilization are gaining an increasingly important role worldwide. Gratefiring is one of the main competing technologies in biomass
