Low or high pressure, dry steam is discharged directly into the process, heat exchanger, process heater, or equipment for a quick, efficient operation. The saturated steam from our boilers can be controlled as to pressure which will vary the temperature and BTU transfer of the steam.
Vacuum steam is the general term used for saturated steam at temperatures below 100°C. Example - Boiling Water at 100 o C , 0 bar Atmospheric Pressure At atmospheric pressure (0 bar g, absolute 1 bar ) water boils at 100 o C and 417.51 kJ of energy is required to heat 1 kg of water from 0 o C to evaporating temperature 100 o C .
A steam generator is used as a source of heat for thawing and de-icing aggregates. This low pressure boiler also speeds up the curing process for pre-cast concrete, pipe, pre-stress, block operations, saturating the curing area with steam, uniformly heating the concrete and speeding up the normal process.
Absorption chillers are available in two types: 1. Single Effect (Stage) Units using low pressure (20 psig or less) as the driving force. These units typically have a COP of 0.7 and require about 18pph per ton of 9 psig steam at the generator flange (after control valve) at ARI standard rating conditions.

Types of High Pressure Boilers. A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas. Boilers vary widely in size from small, portable or shop-assembled units to large furnaces
Jan 16, 2017 · If we select a steam-to-water heat exchanger—also called a convertor—at 30 PSIG entering steam pressure, we get a shorter unit than if we select it at 5 PSIG entering steam. There’s slightly more latent heat in higher pressure steam, but the overriding factor comes from the steam temperature. 30 PSIG steam is 274°F while the 5 PSIG steam
The exhaust steam from the low pressure turbine is condensed to water in the condenser which extracts the latent heat of vaporization from the steam. This causes the volume of the steam to go to zero, reducing the pressure dramatically to near vacuum conditions thus increasing the pressure drop across the turbine enabling the maximum amount of
For the low-pressure steam typically used in heating systems, that ratio is 1,194 BTUs for every pound of steam the system provides. If your boiler supplies 400 pounds of steam per hour, for example, you would multiply 400 pounds by 1,194 to arrive at a figure of 477,600 BTUs.

Although vertical boilers are available at this capacity, most industrial plants elect to go with a horizontal firetube boiler. The horizontal firetube boiler offers a much longer lifespan, safer operation and more stable firing. 50 HP boilers can be purchased in low pressure (15psi) steam, high pressure (150 - 300psi) steam, hot water and high
As water passes through the coil, the heat is transferred from the hot gases which causes the water to convert to steam. The generator design does not utilize a steam drum where the steam of a boiler has a disengagement area from the water in so the use of a steam/water separator to achieve 99.5% steam quality is required.
The question has already been answered when the generation is for a short duration. However in the real world of steam generation, the water used, even when strictly purified, contains some materials that do not leave the boiler with the steam.
PG−5.5 The use of austenitic alloy steel is permitted for boiler pressure parts that are steam touched in normal operation. Except as specifically provided in PG−9.1.1, PG−12, and PEB−5.3, the use of such austenitic alloys for boiler pressure parts that are water wetted in normal service is prohibited.7
Main steam is at 2,000 psia, 1,000 F, and has an enthalpy of 1474.1 Btu/lbm. The steam extraction (cold reheat) pressure is 300 psia, which equates (isentropically) to a cold reheat temperature of
In a plant where low-pressure steam is currently being exhausted to the atmo- sphere, a mechanical chiller with a COP of 4.0 is used 4,000 hours per year (hr/ yr) to produce an average of 300 tons of refrigeration.
