CFBC Boiler Start Up Procedure
07-12-2017
The methods of combustion employed in the boilers vary depending on factors such as fuel used, type of boiler, capacity of boiler in terms of TPH etc. Among the several methods are- Hand Fired over Static Grate or Mechanical stokers such as Low Ram, Chain Grate, Travagrate, etc. In boilers having large capacities, i.e. 30 TPH and over, pulverized fuel is combusted through a jet of air in specific burner. One of the popular and efficient method of combustion used in today’s boilers/heaters is the concept of Fluidised Bed Combustion (FBC). A descriptive feature for the popularity of FBC technology is it can work efficiently with low grade coal quality for example Indian Coal, which generally has very high ash (up to 70%) and high moisture (up to 40%).
The fluidized bed exhibits a few properties as liquids do
1.The bed levels itself within the compartment.
2.Objects when placed in the bed will either stay over the top or sink in the bed depending on its density.
3.Addition of solid powder material gets distributed uniformly.
4.The heat gets uniformly transferred throughout the bed when generated within a specific part.
The technology of FBC has been used in the Chemical Engineering and processes for long time but its use in combustion has begun since last twenty years. While using the phenomenon of FBC in boilers and heaters, a fuel like coal, husk is continuously fed to the sand bed which is maintained at a temperature higher than required to ignite the fuel, which keeps the combustion self sustained. With control of air stream, velocity of air, its turbulence, feed rate of the fuel, high temperatures and efficiency can be achieved. This control of above mentioned properties if properly cared then the problem of clinker formation, fusing of sand and fuel to stones, can be avoided.
Comprehensive discussion on the Start-up procedures, Stopping, Clinker are very beneficial to amateur boiler/ heater operators and engineers looking forward to work with Fluidized Bed Combustion Boilers/ Heaters. These procedures have been developed by professional operators of AFBC boilers. Although in today’s times, most high capacity boilers/heaters have advanced operations methods like SCADA, PLC which are programmed to automatically control many parameters based on current data, this basic knowledge is primarily important to understand the working of any FBC system. I have personally worked with several makes of FBC boilers and heaters all of which need this basic knowledge of operation apart from knowledge of boiler, heater, auxiliary equipments, instruments etc. found in the complete Heating system.
