Water Tube Boiler - Definition, Components, Working …

A reasonably well-insulated shell or water-tube boiler of 5 MW or more will lose between 0.3 and 0.5% of its energy to the surroundings. This may not appear to be a large amount, but it must be remembered that this is 0.3 to 0.5% of the boiler's full-load rating, and this loss will remain constant, even if the boiler is not exporting steam to the plant, and is simply on stand-by.

Plant Engineering | Maintaining boiler safety

Low-water trips protect boiler pressure parts by shutting down the fuel combustion process, eliminating high temperatures in the furnace when the natural circulation cooling process is interrupted. Control of the boiler drum level is sophisticated, and even the best-tuned control systems cannot always prevent a low-water condition.

Water Tube Boilers | Spirax Sarco

Combustion control techniques reduce the amount of NOx emission by limiting the amount of NOx formation during the combustion process. This is typically accomplished by lowering flame temperatures. Combustion control techniques are more economical than post combustion methods and are frequently utilized on industrial boilers requiring NOx controls.
