BOILER MAINTENANCE AND SAFETY VALVES
[attachment=20091]
If we not check and maintained boilers properly then we have different problems or may be boiler is dangerous or harmful. Each year many accidents occur and approximately 43,000 industrial boilers are out of duty. On boiler breakdown we spend thousands of dollars and hundreds of lives.
Regularly inspection of boilers can extend the life of vessels.
Boilers have many features designed to prevent accidents and keep the boilers in working condition.
SAFETY FEATURES
• Safety valves are most important for the safety of boilers. Safety valves are used which are used to open the valves or close the valves if the system fail. Every steam and hot water heating boiler must have at least one or more safety valves because the burner requires relieving the pressure generated.
• Internal corrosion is also a very important factor affecting the boiler. It causes the freezing or closing the safety valves. This is most commonly named as “Simmering”. This problem is intolerable and must be corrected immediately.
• The working of the boiler should not be close to its full capacity because then the safety valves will operate most often and this can cause it to leak slightly.
TIPS FOR IMPROVING THE EFFICIENCY AND PERFORMANCE
A small decrease in boiler’s efficiency can cause a very high degree of increase in energy costs. To improve we can take the
Following steps:
• Optimization of the air to fuel ratio should be optimum. Excess of air and oxygen wastes a lot of energy. If the air and oxygen fuel is not sufficient then all the fuel will not be able to burn.
• Optimize water treatment, before being pumped into a boiler; feed water is treated to remove dissolved oxygen and other impurities that might cause corrosion or buildup of sediment, both of which reduce boiler efficiency. These impurities waste energy, as they provide routine boiler blow downs. The water treatment cleans the water going into a unit, the fewer boiler blowdowns that will be necessary.
