Occupational Hazard Datasheets - Operator, boiler

Boilers work at a high heat adjacent to pressurized vessels which put their operators at a risk of burns and explosions. Burning of fuel used in boilers may lead to fires, carbon monoxide poisoning, etc. Boiler operators come into contact with various substances used in boilers (fuel, water additives, etc.) which may lead to eye and skin disorders.

Pulverized coal-fired boiler - Wikipedia

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal that is blown into the firebox. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels. Coal is ground to the size of a fine grain into the boiler, mixed with air and burned in the flue gas flow. Biomass and other materials can also be added to the mixture. Coal contains mineral matter which is conv
