Question

scale formation in boiler cause
1. No loss of heat
2. wastage of heat
3. increase in efficiency
4. none of the above​

Answer 1

Explanation:

options 2) Wastage of heat

Answer 2

SCALE FORMATON IN BOILER CAUSE WASTEAGE OF HEAT

Explanation:

• this scale formation is a deposit which forms when constituent limit exceeds directly on heat transfer surfaces
• scaling is basically a accumulation of mineral deposits on the interior surfaces of water lines and containers
• this often occured when the water is contaning bicarbonates and carbonates of calcium and magnesium is heated.
• the resulting compounds that was formed precipitate onto the tube surfaces.
• Such deposits may contain  magnesium, phosphate, isilica, calcium,iron.
