Solved: 2. (a) Dry Saturated Steam At A Temperature Of 180

2. (a) Dry saturated steam at a temperature of 180ºC is to be produced in a fire tube boiler from the cooling of 50 000 kg h–1 of flue gases from a pressurised combustion process. The gases enter the tubes of the boiler at 1600ºC and leave at 200ºC. The feed water is externally preheated to 180ºC before entering the boiler.

Boiler types - Marine Engineering - Beyond Discovery

Apr 19, 2021 · The dry pipe is located in the steam drum to obtain reasonably dry saturated steam from the boiler. This is then passed to the primary superheater and then to the secondary superheater. Steam temperature control is achieved by the use of an attemperator, located in the steam drum, operating between the primary and secondary superheaters.

Fuzzy Control of Boiler Superheated Steam Temperature

II. PID CONTROL OF BOILER SUPERHEATED STEAM TEMPERATURE Boiler superheated steam temperature control is to keep the steam temperature within a certain range. Generally, the fluctuation of steam temperature shall not exceed ±(5~10)℃, and it is better within ±5℃. As the saturated steam is sent out from the boiler drum, and the superheated

SATURATED STEAM - THE MARCET BOILER

SATURATED STEAM - THE MARCET BOILER. The TD1006 Marcet Boiler is a simple experiment to show the relationship between pressure and temperature for saturated (wet) steam for comparison with published results. The apparatus consists of a rigid frame containing an insulated pressure vessel (boiler) and an instrumentation and control unit.

Apr 18, 2018 · STEAM TEMPERATURE CONTROLS IN POWER PLANT BY COIL IMMERSION IN BOILER DRUM. In this method some portion of superheated Steam is passed through a coil immersed in boiler drum. A bypass valve is provided to control flow of steam to drum. When temperature of steam is high control valve closed so more steam is pass through the coil immersed in boiler drum.

Basic Desuperheating Theory | Spirax Sarco

Basic steam desuperheating. Desuperheating is the process by which superheated steam is restored to its saturated state, or the superheat temperature is reduced.Most desuperheaters used to restore the saturated state produce discharge temperatures approaching saturation (typically to within 3°C of the saturation temperature as a minimum).Designs for discharge temperatures in excess of 3°C

Steam Heating System Operating Temperature

However 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
