Turbines vs. Reciprocating Engines | Power Engineering

When it comes to boilers and the insurance world, you first need to understand who's covering what. A boiler is normally covered by two different insurance policies. One is the boiler /machinery (B/M) coverage for the pressure side, meaning the tubes, drums, water level controls and safety relief valves.

Difference Between Steam Generator And Boiler

Figure 2.1 shows a USC/A-USC cycle configuration with a single reheat steam cycle. 4 An A-USC may have steam conditions approaching 27.6 MPa, 730 °C/760 °C (4000 psia, 1350 °F/1400 °F). The deployment of this steam cycle is currently under development and is expected to be available in the 2015–2020 timeframe. 5 The present limitation to using steam temperatures to these levels is

Reheat Steam Cycle - an overview | ScienceDirect Topics

Aug 26, 2011 · Heat recovery steam generators behind gas turbines are either unfired or fired. In the fired category, depending on the firing temperature, HRSGs are classified as supplementary fired or furnace fired. Typically, turbine exhaust gases have 14% to 15% by volume of oxygen in the exhaust, which can be used as combustion air.

Repowering Revisited | Power Engineering

Depending on a number of factors including coal properties, boiler efficiency typically ranges between 87% and 89% while firing coal. The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal

HRSG Boilers - Rentech Boilers

An HRSG is a kind of heat exchanger that recovers heat from the exhaust gases of a gas turbine to an extreme degree. The heat is recovered in the form of steam which is served as the power source of a power-generating steam turbine. For the heat-transfer tubes of an HRSG, finned tubes with excellent heat-transfer performance are employed.

Top Ten Boiler and Combustion Safety Issues to Avoid

But if the fuel is not in cascade, the boiler master output tracks the fuel flow SP. If the boiler master is in manual or tracking, its bias tracks the difference between it and the plant master output. If there is only one boiler, the output of the plant master is the boiler master and no bias is needed.
