Question

How much capacity of heat is possible to produce by the travelling grate stoker?

(a) 80 * 10^6 kJ/m^2.hr

(b) 40 * 10^6 kJ/m^2.hr

(c) 25 * 10^6 kJ/m^2.hr

(d) 65 * 10^6 kJ/m^2.hr

I had been asked this question in final exam.

My question is based upon Type of Stokers topic in portion Steam Power Plant of Energy Engineering

Answer 1

Right option is (a) 80 * 10^6 kJ/m^2.hr

Best explanation: The spreader stoker has wide applications with respect to the fuels used as well as to the boiler sizes. A wide variety and poor quality coal can be burnt efficiently with this type of stoker. This type of stoker can be used for boiler capacities of 80 tons to 150 tons of steam per hour. The heat release rate of 80 * 10^6 kJ/m^2 hr is possible with travelling grate.
