Cereal grain combustion in domestic boilers

 · Sustained grain combustion in domestic boilers was feasible but problematic, the main impediment being clinker formation with ash agglomeration. Clinker formation was lowest for oats which burned easily with fewer operational problems. Triticale displayed reasonably good combustion characteristics and also ignited easily.

Clinker Formation in Solid Fuel Fired Boilers

Clinker may reduce the boiler operating efficiencies. Clinkers have been a recurring problem in all solid-fired boilers for long. Clinkers, also known as slag, and in coal fired boilers consist of the noncombustible elements and minerals found in coal that melt and fuse together as lumpy ashes from coal combustion.

What Causes Clinkers in Coal Fired Boilers?

Clinkers, or slag, are made up of elements and minerals found in coal which are non-combustible. When burnt, they melt and fuse together, forming lumpy ashes. For as long as we have operated coal boilers, clinkers have been a recurring problem, occurring in small stoves used for heating a home right up to giant commercial/industrial boilers.

What Causes Clinkers in Coal-Fired Boilers? | Hunker

 · Clinkers are a problem when they form in coal-fired boilers. Coal-fired boilers were once commonly used in American homes in the days before electricity. Coal burns hotter and longer than wood, but coal, like wood, can produce leftover chunks called clinkers. To make the boiler run more efficiently, the clinkers must be removed.
