Air inlet as the air supply, air pulverize requiring fixed temperature for the process, so before entering the air through the pulverize in pprimary heating wwater heater up to a certain temperature.
MSHA Heat Stress Heat Stress in the Mining Industry
You are more likely to suffer from heat stress if you are beginning a new job in a high heat environment, have had a heatrelated illness before, use personal protective equipment (respirator, suit), take certain medication or are over 45 years old. Why is heat stress a health hazard? Severe heat stress may lead to death if not treated right away.
IMPROVING BOILER EFFICIENCY BY USING AIR PREHEATER .
Abstract: Air preheater is a heat transfer surface in which air temperature is raised by transferring heat from other media such as flue gas .Hot air is necessary for rapid combustion in the furnace and also for drying coal in milling plants.
