The Temperature in Your Boiler and the Dangers
Once a boiler starts to go over 212°F, you can face serious problems. Watch out for overheating. If you notice that your boiler’s temperature is going higher than the above settings, you have a major problem. If a boiler has reached 220°F, a sudden drop in pressure could cause the tank to burst. Overheating also is the main cause of leaking.

How to Run a Coal Fired Boiler at the Best Efficien
Today many of the boiler designers reduce this loss by recovering the heat after low temperature superheater by larger economizer and air pre-heaters. As designers go for lower and lower exit gas temperature the size of air pre-heaters go up. Boiler tuning for optimal Dry gas. Keep an optimal excess air level, generally about 20% in a coal

File Size: 239KB Water feeders protect boilers by maintaining a safe water level. Low water cutoffs work in coordination with water feeders to detect the fluid level in hot water and steam boilers. If water level falls below the minimum safe operating level, the water feeder is initiated. Water feeders can be automatic (electric) or manually operated.

The time of pulverized coal-air mixture in a furnace can be divided into three periods: 1. drying, devolatilization and ignition of coal particles, which requires 0.2–0.3 s, 2. Intensive mixing and burning of pulverized coal-air jet during 0.5–1.5 s on a distance of 1–5 m with formation of flame kernel of the temperature 1500–1600 °C, 3.
