Introduction to Boiler Operation

2.1 Boiler Design and Construction Boiler: A boiler is a closed vessel in which water is heated, steam is Usually boilers are coal or oil fired. A boiler should fulfill the following requirements: control the discharge of hot gases from the chimney and thereby the supply of air to the grate is controlled. The chimney may also be provided

ability for rapid load change rates are expected from a modern coal-fired power plant. This requirement is challenged by practical design considerations that higher steam parameters increase the wall thickness of boiler components and thus increasing thermal-mechanical stress potential and therefore limit operational flexibility.

11.3 Chimney System Design Chimney System Sizing A chimney must be designed properly to control draft and remove the gases produced by combustion in a boiler, furnace or fireplace. Draft is negative gauge pressure measured relative to atmospheric pressure. Chimney design balances buoyancy forces against friction losses.

Pulverized Fuel 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

Jul 05, 2009 · Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss. There are a few minor losses in boiler which can also
