Ankur is very correct in pointing out the limitations of a Fire Tube Boiler (also known as a "Scotch Marine" boiler). I have installed and employed a lot of these types of boilers and have found that the usual top steam pressure generated by this type is approximately 75 to 100 psig (5 to 7 barg).

Flue gases on steam boiler plant are not condensed, therefore the actual amount of heat available to the boiler plant is reduced. A pressure jet burner is simply an orifice at the end of a pressurised tube. Typically the fuel oil pressure is in the range 7 to 15 bar. and to use this to fire the boiler when gas is not available. This led

Chapter 9 O&M Ideas for Major Equipment Types 9.1 . Introduction . 126.96.36.199 Fire-Tube Boilers . Fire-tube boilers rely on hot gases circulating the small tubes in the water-tube boiler can withstand high pressure better than the large vessels of a ire-tube boiler. In the water-tube boiler, gases low over water-illed tubes.

The weight of a cubic foot of water as it enters the boiler from the injectors is 60 1/8 pounds, while a cubic foot of water at 190 psi steam pressure, or 383 degrees Fahrenheit, is 54 1/4 pounds, or 9% lighter than the water at 200 degrees delivered into the boiler from the injector.
CHAPTER TWO: Boiler Operation Maintenance & Safety Study
In fire tube boiler the hot products of combustion pass through the tubes, which are surrounded, by Coal or oil can be used as fuel in this boiler. If oil is used as fuel, no grate If the feed water pressure is less than the boiler steam pressure then this valve remains closed and prevents the back flow of steam through the valve.

Tube Failures in High Pressure Boilers
Tube failure in high pressure boilers follow a normal bath tub curve, with higher rate during initial operation period, stabilizing to a lower rate during the normal operating period and again increasing as the boilers age and cross ten to fifteen years of operation.

And whether thermo steam boilers is water tube, or fire tube. There are 49 thermo steam boilers suppliers, mainly located in Asia. The top supplying country is China (Mainland), which supply 100% of thermo steam boilers respectively.
Stack Temperature & Efficiency: The Relationship | O'Brien
Normally, as the operating pressure increases, the stack temperature in a clean, well-tuned boiler will also increase, anywhere from 24 to 38 degrees over the saturated steam temperature. As an example, a 3500kw boiler burning natural gas, firing at 100%, 200 KPa operating, and with a 27 degree C ambient, will indicate a stack temperature of
