Operating Controls - National Board of Boiler and Pressure ...A second device is used to prevent the boiler from exceeding the maximum allowable working pressure (MAWP) indicated on the boiler nameplate. Hot-water boilers require a device which senses water temperature and cycles the burner or other source of heat in order to maintain a consistent, predetermined operating temperature.
Boiler and Condenser Pressures - Rankine CycleAssuming that the maximum temperature is limited by the pressure inside the reactor pressure vessel, these methods are: Boiler and Condenser Pressures As in the Carnot, Otto and Brayton cycle, the thermal efficiency tends to increase as the average temperature at which energy is added by heat transfer increases and/or the average temperature ...
Pages - Boiler Ratings - Spirax SarcoThe 'from and at' rating is widely used as a datum by shell boiler manufacturers to give a boiler a rating which shows the amount of steam in kg/h which the boiler can create 'from and at 100°C',at atmospheric pressure.
Chapter 3a. Boiler And Unfired Pressure Vessel Regulations(b) When a boiler system is comprised of boilers with different maximum allowable working pressures having minimum safety valve settings varying more than 6% and connected so that steam flows toward the lower pressure boiler, the boiler system must meet one of the following requirements:
High-pressure steam locomotive - WikipediaA high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa).

What do you mean by working pressure of a boiler? - QuoraWorking pressure is the same thing as the maximum allowable working pressure or MAWP. The two terms are used interchangeably. Per the link below - MAWP is the maximum pressure at which the vessel or equipment is allowed to function at a specif...
What is the safe pressure for a hot-water-heating system?The maximum pressure I am allowed it to get to is 30-psi, because, at that pressure, the pressure relief valve will open. This is typical of residential hot-water boilers. As far as temperature is concerned, my boiler will shut off if the temperature exceeds 205 F. THey do not want the water in there to boil.
