· PDF filePulse Firing reduces the requirements for excess air. • Pulse Firing operates the burner on/off or high/low. • When the burner is pulsed, it delivers the maximum velocity • During off or low modes, the burner operates at an enhanced turndown, typically 20:1

Locomotive boiler is the horizontal fire tube boiler in which hot gases pass through the tubes and water surrounds them. Transferred heat from the gases to water and then converted into steam. It may also be used as a stationary boiler. What is a Cochran boiler? A vertical boiler with horizontal fire-tubes is a type of small vertical boiler, used to generate steam for small machinery. B. What is a fire tube and …

15-03-2020· As the quantity of required air and fuel both are less, loss of heat in this method of boiler firing is much less. Hence temperature can easily be reached to the designated level. As the combustion is most efficient pulverized coal firing increases the overall efficiency of a steam boiler. As handling of lighter coal dust is much easier than the handling of heavier coal chips, it is quite easy to control the …
