sON Continuous ash discharge stoker with undergrate Zoning Background Continuous ash discharge (Cad) stokers are regularly installed in coal fired industrial boilers part.

Stoker Fired Boiler are classified according to the method of feeding fuel to the furnace and by the type of grate. The main types of stokers are: Travelling Grate or chain grate Stoker Boiler. In Travelling Grate boiler coal is fed at one end of a moving steel chain grate.

The Detroit® Hydrograte Stoker offers reliability and lower maintenance costs. The spreader firing principle is the most widely accepted, proven and user friendly means of burning biomass fuels. Fine particles of fuel are burned in suspension assisted by the overfire air system.

The 2-drum bottom-supported boiler is offered in a wide variety of fuel firing combinations including gas/oil burners, solid fuel suspension burners (for sander-dust), and continuous ash discharge stokers including traveling grate, air and water-cooled vibrating grates.

Detroit® Ash Handling Systems are designed for effective, economical and trouble free disposal of ash from units burning coal or solid refuse fuels. Ash from the various collecting points is pneumatically conveyed to the ash storage silo and is unloaded at regular periods for final disposal without creating a dust nuisance.

There are some ash handling equipment are installed in stoker boiler such ash chute hopper, air plenum hopper, ash cooler, ash conveyor, and the equipment of ash handling can be mechanically, hydraulically, and pneumatically.

A continuous ash discharge (CAD) stoker is normally used for this combination of fuels. In assessing an acceptable grate rating for biomass fuel firing, the effective moisture of the biomass is the key parameter required whilst the grate rating for coal is a function of its reactivity.

The stoker accepts coal from the bulk storage, levels it to a uniform height, ignites it, provides air for combustion and discharges the spent ash. The reliable operation of the stoker is critical to the performance of the boiler, and will be discussed in some detail.

When the company ordered a new 227 ton/hr Thermal Energy Systems boiler it selected a TES Continuous Ash Discharge Stoker for it to cope with the highly variable ash loadings that it experiences because of its particular cane land conditions and to minimise the risk of peak emissions that may arise from stokers employing intermittent ash ...
