BAGASSE FIRED BOILERS. By G. E. Gamble. "Bagasse" is the term applied to the waste fibres of sugar cane, after the sugar juices have been extracted in the mills. It consists of fibre and water, plus a certain amount of sugar juices. The amount of fibre and moisture varies considerably, being largely influenced by the nature of the soil, type of
Boiler operating practices that reduce emissions of oxides of nitrogen tend to increase formation of clinkers. Other contributors to clinker formation include failure to remove soot and other deposits, poorly pulverized coal, and improper burner adjustments that result in inefficient mixtures of air and fuel.
following reasons. To ensure stable combustion and prevent the formation of carbon monoxide (CO) which is highly poisonous and explosive. To allow for variations in the required air-to-fuel ratio due to combustion air temperature, pressure and humidity changes. To allow for slight variations in the chemical composition of the fuel gas and its

For example, boilers are often referred to as oil-fired, gas-fired, coal-fired, or solid fuel-fired boilers. Coal-fired boilers can be further divided based on the equipment
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7-2,000 kPa or 1-290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

of bagasse fired boilers used in the industry could be grouped into step grate type, horse choe type and spreader stoker type. (i) Fuel and Boiler Characteristics The main source of air pollution from sugar industry is the bagasse fired boiler. The major pollutants are sulfer dioxide, nitrogen oxide and carban monoxide.

Resembling volcanic ash and lava, clinkers occur in the high-temperature furnace area of the boiler. Coal boilers draw their combustion air from the bottom, up through the combustion grate. Lots of large clinkers on the combustion grate can hinder air passage, increase operation and maintenance costs and even force shut-downs of the boiler for
Clinkers, also known as slag, consist of the noncombustible elements and minerals found in coal that melt and fuse together as lumpy ashes from coal combustion. Boiler operators consider clinkers
Because two reasons , A) only a tiny wind going through fuel material (less than a third of direct-fired burner 's air volume); B) Much more fuels inside the gasification chamber (more than five
and/or furnace will need to be de-rated to prevent clinker and slag formation and boiler fouling. Introduction . Coal is often used as an auxiliary fuel in biomass fired co-generation power stations such as those installed in the cane sugar industry. These stations typically employ 10 to 75 MW turbo-alternators coupled to 75 t/h to 250 t/h boilers.
Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm (0.001 in). Coal burns in suspension, like the combustion in an oil- or gas-fired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace volume using burners that look somewhat like oil
Bailly Generating Station (BGS) Boiler #7 is a 160-MW e (net) cyclone fired unit. At MCR it generates some 151.3 kg/sec (1.2 × 10 6 lb/hr) of 165.5 bar/538°C/538°C (2400 psig/1000°F/1000°F) steam. At the time of testing, the plant fired a blend of 70% high-sulfur Illinois Basin coal and 30% low-sulfur Western bituminous Shoshone coal.
With careful management and using modern, highly efficient bagasse-fired boilers it is possible to produce more electricity than is required by the factory. It may be possible to sell this excess electricity to the grid or other users, generating another source of income for the factory.
