Designer, manufacturer and distributor of standard and custom low pressure steam generators. Gas or oil fired low pressure steam boilers or pressurized water boilers are available in horizontal configuration with steam production from 220 lbs./hr to 6,615 lbs./hr and operating steam pressure rating of 14.5 psig.
The main difference between saturated and superheated steam is that the saturated steam is at a two-phase (liquid and gas) equilibrium temperature – so could contain water droplets, whereas the higher-temperature superheated steam is a high enthalpy gas (called high quality steam as there are no water droplets in it). Superheated steam has a
Jan 03, 2018 · MHPS also has hit the 64% efficiency mark. "In 2017, MHPS announced the introduction of a gas turbine capable of 400 MW simple cycle, and 575 MW and 64% efficiency combined cycle, the biggest
pressure. As it flows to the surface, the fluid pressure decreases and some of the hot water boils or "flashes" into steam. The steam is then separated from the water and used to power a turbine/generator unit. The remaining water and condensed steam are injected through a well back into the reservoir. Binary-cycle power plants
The clean steam generator is use to avoid chemicals normally use in steam water treatment, in steam injection process such as humidification and sterilization. It is basically a shell and tubes steam to steam heat exchanger design to use higher steam pressure from the steam boiler and generate lower clean steam pressure for the process.
technology is a reliable and economic choice for stand-alone applications and as a prime mover for CHP applications (EPA, 2015). Reciprocating engines are available in multiple sizes, ranging from few kWs up to several MWs for DG applications. They can produce hot water, low pressure steam, and chilled water by means of an absorption chiller.
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.
Electrification is the process of powering by electricity and, in many contexts, the introduction of such power by changing over from an earlier power source. The broad meaning of the term, such as in the history of technology, economic history, and economic development, usually applies to a region or national economy.
High-pressure transmit and low-pressure use is the key features of steam. It mostly equips PRV (Pressure Reducing Valve) in use site if there is heat demand in following process. However, the energy loss of the pressure is also the economic loss. Today, these waste heat sources are all useful for screw expander generator.
The combined-cycle system includes single-shaft and multi-shaft configurations. The single-shaft system consists of one gas turbine, one steam turbine, one generator, and one Heat Recovery Steam Generator (HRSG), with the gas turbine and steam turbine coupled to the single generator on a single shaft.

Section 4. Technology Characterization – Steam Turbines . 4.1 . Introduction . Steam turbines are one of the most versatile and oldest prime mover technologies still in general production used to drive a generator or mechanical machinery. The first steam turbine used for power generation was invented in 1884.
Extraction back pressure turbines (Figure 3-25) can be used when two or more kinds of process steam are required. High-pressure steam is supplied through the extraction openings, and low-pressure steam is supplied as the turbine exhaust. Electric output depends on the demand for process steam.
Steam Pressure. Steam pressure is a very important property of steam when learning about steam turbine generators and gas laws.. Water in a gaseous state (steam) consist of water molecules that are more spread out and moving much more rapidly than the molecules of liquid water or ice.
The topping cycle really is the only economic cycle of the two. The main heat source generates high-enthalpy steam and electricity. Low-enthalpy steam is taken from an intermediate turbine stage or the turbine exhaust for process requirements. If the steam is taken from the turbine exhaust, this is called a back pressure turbine.
Sitong gas fired steam generator is vertical type with high thermal efficiency (96%) and quick steam generation (3~5 minutes).

Oct 28, 2014 · Steam Boilers OR Steam Generators 1. Boilers (Steam Generators) 2. Definition of a boiler • A boiler is a device used to generate steam at a desired pressure and temperature by transferring heat energy produced by burning fuel to water to change it to steam. • It is a combination of apparatus used for producing, furnishing or rec
The low-pressure steam can be used for district heating, if demand exists, but cannot be used to generate additional power. The total efficiency, or ratio of energy input versus electricity energy produced, for conventional power plants is around 34%. A combined cycle plant, by contrast, generates power directly from a gas generator when gas is
Utility steam and gas turbine sump capacities can range in size from 1,000 to 20,000 gallons, which drives the economic incentive for a long-life lubricating oil. Low turbine oil makeup rates (approximately five percent per year) also contribute to the need for high-quality, long-life lubricants.

Steam Driven Generators: Steam Turbines and Electric Generators. A steam turbine driven generator, sometimes known as "turbo generators", can be best explained by understanding a steam turbine and a generator separately. A steam turbine is a steam-driven driver. Water is heated at an extremely high temperature to convert it into steam.

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.
The saturated steam thus formed is further superheated. After passing over the heating surfaces at various zones the flue gas is cooled and discharged to the atmosphere through a stack. The primary function of a steam generator is to generate steam under pressure, but modern steam generators are also required to do the following: i. Ensure
