The direct steam option is intended for sites which already have a steam supply, or for larger autoclaves that require a powerful stand alone steam generator. An external steam feed enters the unit as per the illustrated diagram. This option is available on all Astell autoclaves from 95 litres and above. To order direct steam, the last digit of

File Size: 1MB In general steam heating is used to. change a product or fluid temperature; maintain a product or fluid temperature; A benefit with steam is the large amount of heat energy that can be transferred. The energy released when steam condenses to water is in the range 2000 - 2250 kJ/kg (depending on the pressure) - compared to water with 80 - 120 kJ/kg (with temperature difference 20 - 30 o C).

Steam Production From steam tables we can see that the total heat of steam does not vary a great deal as the boiler pressure increase The boiling point (b.p.) increases as the pressure increases Thus the sensible heat increases as the pressure increases, and the latent heat decreases Boiler pressures are expressed in psia, psig, bar, kg/cm2

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.

Ethylene Processing — Dilution Steam Systelll PROBLEM In an ethylene plant, fouling of the Dilution Steam System (DSS) Heat Exchangers can be a source of high maintenance and operating costs. Common problems include: Increased steam usage Reduced efficiency in low, medium, and high pressure steam systems Losses of recoverable pyrolysis gasoline

Horizontal drum type OCC™ Horizontal drum type HRSG features vertical tube, natural circulation design with horizontal gas flow. HRSGs can be customised as single, dual or triple pressure with or without reheat. Design features on the OCC™ HRSG have been refined over decades based on cutting-edge R&D and field experience.

The steam generator is a very important component of a nuclear power plant. Historically, vertical steam generators came to be used abroad and horizontal steam generators in our country.

Dec 04, 2001· Vertical Steam Generator (Click to expand): The vertical steam generators generally have a feedwater ring supply header on the outer edge of the steam generator. The water is directed downward and flows along a wrapper sheet then is directed upwards to flow along the steam generator tubes where the water picks up heat, increasing in temperature until boiling occurs and the water is …

File Size: 1MB The control kits for KOHLER steam generators consist of a control and steam head. Control regulates time, temperature, on/off and the Power Clean feature. The steam head releases steam from the generator into the shower. With a variety of finishes available, it's easy to …
