Product Category : Boilers & Boiler Parts
Thermax Babcock & Wilcox Limited is offering Biomass and Multifuel Grate Fired Boilers. The Biomass and Multifuel Grate Fired Boilers are manufactured to improve profitability by optimum usage of Solid wastes generated in the plant.
The Biomass and Multifuel Grate Fired Boilers feature flexible design that offers:
Indoor & outdoor installation.
Travelling grate or dumping grate option.
Membrane wall / tube & tile construction.
Auto controls or remote manual control option.
Capacities upto 250 TPH., Pressure upto 135 kg. / cm2. And temperature upto 515degC.
Multifuel firing-including Bagasse, Hulk straw, coffee ground, cane tops coconut shells, lignite, coal, pith, wood chips as well as oil and gas support.
Travelling Grate of the Biomass and Multifuel Grate Fired Boilers ensures uninterrupted combustion and also:
Overlapping grate design prevents air leakages.
Dumping Grate is also offered optionally on request.
Grate can be maintained without shutting down the boiler.
Grate speed can be varied continuously in range 0-15 m.Hr.
Continuous ash discharge system avoids dependence on operator`s judgement.
Membrane panelled furnace design of these Biomass and Multifuel Grate Fired boilers features the following:
Requires no refractory in furnace walls and eliminates associated maintenance.
Results in quicker boiler commissioning due to reduced site welding, simplified handling/erection.
Machine welded membrane wall furnace forms a gas tight enclosure preventing ingress of unwanted excess air.
Tall furnace for complete combustion offers some other features such as:
Tall furnace increases residence time to flue gases, allowing bagass to burn completely about grate, before gases enter superheater zone.
High pressure deep penetration secondary air jets are strategically located at multiple levels on furnace walls, ensuring proper turbulence and good mixing of volatiles with air and complete combustion in furnace.
Some other features offered by the Biomass and Multifuel Grate Fired boilers are:
High efficiency steam separators ensure steam purity.
Variable speed bagasse feeder allows fine control of fuel feed.
Modulating cyclomotor to ensure even distribution of fuel on grate.
Optimum design and selection of auxiliary equipments to ensure the highest operational efficiency and availability of the plant.
