pressure and low velocity, under circumstances where low leakage is not required (Class III). The VD-1310 is not designed for outdoor air. The VD-1320 is a formed two-piece blade for appliions as a low leakage control damper (Class I). The VD-1330 is anas a
3 SECTION I - GENERAL INFORMATION 1.1 Introduction The function of a surface condenser is to create the lowest possible turbine or process operating back pressure while condensing steam. The condensate generated is usually recirculated back into the boiler
Mention “HRSG” and most people in the power business think of triple-pressure units in service at large coined-cycle plants. Articles in the trade press and papers presented at major industry conferences focus on these units. During the recent building boom
The Protector Series 150 kW is strong, dependable, and eco-friendly with the capability to handle days of use at a time and no refueling. Protect your inventory and equipment assets, as well as customers and staff, with our natural gas or LP generators. With units
3.Design pressure is the condition of coincident temperature and pressure that is expected in a normal condition. 4.Maximum Allowable Working Pressure is the maximum pressure that is permissible at the top of the equipment or vessel in normal operating
A high-pressure boiler is defined as a boiler in which steam or vapor is generated at a pressure equal to or greater than 15 psig, or a boiler in which water is heated at a temperature of 250°F and a pressure greater than 160 psig, when water is heated for use external to the boiler itself.

Heating 16 Steps to Proper Boiler-Feed-Pump Selection These steps apply to pump selection for an industrial steam boiler with a horsepower range of 100 to 1,200 and a design pressure of 150 to 500 psig. Training Calendar of HVACR Training and Eduion Events
Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it
Division 3 - Alternative Rules for Construction of High Pressure Vessels, provides requirements applicable to the design, fabriion, inspection, testing, and certifiion of pressure vessels operating at either internal or external pressures generally above 10,000

Pressure relief devices are used to provide a means of venting excess pressure which could rupture a boiler or pressure vessel. A pressure relief device is the last line of defense for safety. If all other safety devices or operating controls fail, the pressure relief device must be capable of venting excess pressure.
