water tube boiler efficiency calculation

With multiple pressure designs, the water tube boilers can meet the steam supply requirements of 2.5MPa or above. The fire tube boilers, on the contrary, are intended for use at pressures below 2.5 MPa. Fire tube boilers usually have a capacity of below 20t/h, while water tube ones of 20t/h or more as capacity expansion is possible.

Boiler Introduction | CleanBoiler.org

In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Since tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (as high as 3,000 psi) are required.

INCREASING THE ENERGY EFFICIENCY OF BOILER AND HEATER

The water treatment and testing program is critical to ensuring the maximum efficiency and reliable operation of any boiler plant. An upward trend in flue gas temperatures over weeks or months usually indicates that a deposit has built up on either the fireside or waterside of boiler heat-exchange surfaces. The boiler should be inspected promptly.

Improving Boiler Efficiency

Efficiency Improvement - Up to 5 percentage points. Properly operated boilers require a certain amount (10% to 20%) of excess air to ensure complete combustion. However, operating with too much excess air reduces boiler efficiency by heating up and throwing away this "cushion" of excess air.
