pressure steam (800 psig, 700°F) in a biomass/wood-fired boiler, expanding this steam through a back pressure steam turbine to generate power, and using the low pressure steam (150 psig, 400°F) exhausting from the turbine for process needs (Figure 1). Both boiler/steam turbine CHP options are technically identical—a 110,000 lb/hr stoker
The Modulatic® High Pressure Compact Steam Boiler Operating Concept. The Modulatic® steam generator is a once through, forced circulation, water tube boiler in which water under pressure circulates at high velocity through a series of coils while forced draft combustion gases travel across the outside of the coils.

Sep 01, 2006 · Steam pressure: Be careful when the pressure in the steam main is low or zero. Because of the lift after the drip traps, flooding will occur even with some pressure in the steam main. Be especially careful during startup, when boiler goes down and when process loads overwhelm steam capacity. 5. Startup and shutdown: These are critical operations.
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
The advantages using a steam boiler instead of steam generator: Larger capacity- can provide 1 - 400 ton steam boilers for your need Higher pressure-steam boiler can be designed as high pressure or even sub-critical pressures Various types-it can be packaged,assembled, field assembled varying from its actual capapcity
W = boiler capacity (Btu/h, kW) h g = enthalpy steam (Btu/lb, kJ/kg) h f = enthalpy condensate (Btu/lb, kJ/kg) m = steam evaporated (lb/h, kg/s) Boiler Horsepower - BHP. The Boiler Horsepower (BHP) is. the amount of energy required to produce 34.5 pounds of steam per hour at a pressure and temperature of 0 Psig and 212 o F, with feedwater at 0

The MED process can operate with low pressure (0.3-0.5 bar), low temperature (70-90°C) steam by nearly vacuum pressure condition. With lower electric consumption of 1.5-2.5 kWh/m3 than MSF, the typical production cost of MED is around 0.7-1 USD/m3, competitive to RO technology..
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 steam turbine of 51.5 MW power output, turbine condenser, generator and turbine controls have been ordered. The equipments will be installed at Obayashi Kamisu biomass power plant in Kamisu city, Ibaraki prefecture, Japan.
Table 1 shows capacity of a natural gas line for a given initial pressure with a 5% pressure drop. For example, consider a 500 hp boiler, which requires 20,925 cu.-ft. / hr. A 5 psi initial pressure is available for 100 ft. of pipe. To find the correct pipe size, go to the line for initial gas pressure reading 5 pounds. Now move to the
Steam absorption chillers are nominally rated as follows: Single stage: 9 psig at generator flange; Two stage: 114 psig steam input pressure. Capacity ratings are decreased as steam pressure drops below nominal. For example, a nominal 100-ton unit's capacity will drop to 84 tons with 78.5 psig steam. Hot Air
The saturated steam from our boilers can be controlled as to pressure, which will vary the temperature and BTU transfer of the steam. We offer a variety of models from 1.5 to 750kW with carbon steel pressure vessels and 1.5 to 120kW in all stainless steel design to match any steam application.
Manual Pressure Pump Generators The HiP High Pressure Generator is a manually operated piston screw pump. It is designed for any application where a liquid* is to be compressed within a small volume to develop pressure.
the turbine generator. The specified operating pressure is the maximum operating pressure at the turbine throttle valve inlet plus the main steam line pressure drop (between the superheater outlet and turbine throttle valve inlet at the maximum continuous rating of the boiler) rounded to the next higher unit of 5 psi (34 kPa gage).
14.1.2 Air-Cooled Condenser (ACC) (Fig. 14.5) Air is used as cooling medium in condensers located either in deserts or in those areas where substantial quantity of CW is rarely available. Exhaust steam from the turbine is condensed on the inside of the ACC by air flowing past the outside of the tubes.
The NUK® High-Pressure Steam Generator is a closed-looped (hermetically sealed) system that produces steam for high-temperature applications. Therefore, this steam generator is able to produce non-toxic process heat while offering the same advantages of a conventional hot oil system .

The vapor generated may be delivered at low-pressure for the industrial progression work in sugar industries, cotton mills, and for generating steaming water that can be utilized for heat up fixing at much low-force. The capacity of the boiler should have ten liters of water and the working pressure must be 3.4 Kgf/cm2 (kilogram-force).

applications with low pressure steam or pressurized hot water. They are available in sizes from 112 to 465 tons and can be used in a wide range of process and comfort cooling applications, using either hot water or steam as an energy input. The chiller is a hermetic design and comes with a factory-mounted microprocessor-based control system.
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 .
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.
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
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
