1.	What does both primary and secondary air ports combined provide in travelling grate stoker?(a) Pressure(b) Evaluating temperature(c) Turbulence(d) Heat intensityThis question was posed to me at a job interview.This intriguing question originated from Type of Stokers in chapter Steam Power Plant of Energy Engineering
Answer» Correct answer is (c) Turbulence For EXPLANATION: The air required for the COMBUSTION is supplied through the air inlets situated the below the grate. The SECONDARY air is supplied through the openings provided in the furnace will be above the grate. The combination of PRIMARY air and over FIRE supplied provide turbulence required for rapid combustion.
