residue burned as fuel in pulp and papermaking facilities is mostly bark, although the residue may also include sawdust, shavings, and rejects from lumber manufacturing processes. In general, the wood residue fuel is called hogged fuel. Most pulp and paper mills burn the hogged fuel in so-called bark boilers. These boilers may also burn coal,

A short summary of this paper. 35 Full PDFs related to this paper. READ PAPER Heat is generated in boiler by combustion process of fuel. The strategy of how to recover this heat depends in part on the temperature of the waste heat gases and the economics involved. Large quantity of hot flue gases is generated from Boilers, Kilns, Ovens and
The boiler system comprises of feed water system, steam system and fuel system. The feed water system provides water to the boiler and regulates it automatically to meet the steam demand. Various valves provide access for main-tenance and repair. The steam system collects and controls the steam produced in the boiler. Steam is directed through

It is the space, above the grate and below the boiler shell, in which the fuel is actually burnt.The furnace is also called firebox. Fire-Tube Boiler A steam boiler in which hot gaseous products of
BOILERS, BOILER FUEL AND BOILER EFFICIENCY. This paper describes the modern boilers in the South African sugar industry. A new equation for the calculation of the net calorific value (NCV) of bagasse is suggested and a distinction is made between boiler design efficiency and boiler operation efficiency. Methods to calculate fuel calorific values and boiler efficiencies from first principles are presented.

The boiler assembly has been modified by adding an air preheater that preheats the air-fuel mixture to 93oC. The use of preheated air-fuel mixture at this temperature improves the boiler
