Fighting the smog in India: biomass instead of air pollution

Jul 09, 2019 The biomass, in this case the harvest stubble, is first shredded and then evenly distributed on a continuously vibrating grate. A water-jacket system provides cooling. The remaining ash is collected and disposed of underneath the grate. At the end of the process, climate-neutral energy is produced from the plant remains from the fields.

TECHNICAL PUBLICATION Babcock Power

Biomass Combustion Technologies allows for control of the airflow to the grate sections for balancing or biasing airflow to the grate. Grate surface oscillation/vibration improves fuel and air mixing, reduces fuel piling and improves fuel burn at a temperature slightly higher than the bed average. The hot gases from fuel combustion are

Biomass Energy Babcock & Wilcox

Since biomass consists of “recently alive” material, burning biomass is CO 2-neutral in the sense that it only releases the quantity of CO 2 that the plant absorbed during growth. Some biomass needs pre-treatment before the fuel is fed onto a combustion grate where it is burned.

DP Water Cooled Vibrating Grate Technology and

The Water Cooled Vibrating Grate is a well-established grate system that provides an intermittent vibration for conveying and distributing fuel evenly, and continuous discharge of fuel ash. It is particularly suited to biomass fuels and has a very efficient carbon burnout rate, which allows an increase in over-fire air, and a subsequent

Medium to large-scale combusters European Biomass

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.
