Answer (1 of 3): To generate steam, you have to reach at least 100C, or 212 degrees Fahrenheit. However, the more pressure that exists in the boiler, the higher the temperature can be. So you could have a boiler with a water temp of 450 degrees F. Someone who

Read MorePressure and temperature. With saturated steam boilers, a physical correlation exists between temperature and pressure. This is represented graphically using what is referred to as a boiling curve. Boiling curve of pure water in pressure-temperature graph (range < 40 bar) This means that the temperature in a saturated steam system can always be

Read More2019/12/30 · High pressure can result from the boiler temperature being set too high. Higher pressures generally cause automatic shutdowns. Modern boilers have built-in pressure release valves. These generally trip at 30 psi and release excess steam to bring the pressure

Read MoreA boiler has a 'from and at' rating of 2 000 kg/h and operates at 15 bar g. The feedwater temperature is 68°C. The use of Equation 3.5.1 will determine a factor to produce the same result: Note: These values are all from steam tables.

Read MoreThe main function of a steam boiler is to producing, storing and troubling the vapor. The liquid contained boiler is nothing but a shell and the heat energy produced while burning of fuel will be moved to water, and then it converts into steam at the required pressure as well as temperature. The main conditions of this boiler mainly include the

Thermal Engineering As for the Carnot cycle, the thermal efficiency tends to increase as the average temperature at which energy is added by heat transfer increases.

Read More2015/3/17 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Read MoreWhile some combination boilers now operate at the pressure of the incoming cold water mains, this is still far below the normal operating pressure of steam-raising boilers. This leaflet applies to steam and high temperature hot water boiler plant (operating above 0.5 bar pressure and a

Read MoreHowever a residential steam boiler pressure is so modest (0.2 psi to 0.5 psi) that the temperature increase above 212 °F will be no more than about 220 °F. A commercial boiler system heating a high-rise building may be operating at much higher pressures, perhaps 20 to 40 psi in order to be able to force steam to 20 or 40 floors of building

Read MoreThe boiler pressure is 12.5 MPa and temperature is 510°C. The condenser pressure is 50.8 mmHg and temperature is 38.4°C. The regenerator pressure is 132 kPa. Habib et al. (1995) indicated that for maximum efficiency of a single reheat cycle, the reheat pressure should be approximately 19% of the boiler pressure.

Read MoreLow pressure steam boilers transfer heat at pressures between 10 and 15 psi with a temperature of 300 F (149 C). This type of boiler is used where there is little need for rapid temperature change, where a consistent temperature is required.

Read MoreAnswer (1 of 6): Nothing much. You would need one boiler generating steam to have a main line with pressurized steam inside. If you bring a second boiler up to mains pressure and open the valve connecting it to the mains, no steam will flow from this second boiler
