Waste Heat Boiler - an overview | ScienceDirect Topics

Process heat recovery boilers, or waste heat boilers, are widely used, particularly on ethylene and ammonia plants and on sulfuric acid and nitric acid plants. This type of boiler has developed as a cross between a conventional shell-and-tube heat exchanger and a firetube boiler.

This control mode is used for boiler start up and shut down and/or special isolated operation. After the steam pressure rises up to the same value as the high-pressure steam header pressure, a controlled signal must be transferred from the superheater outlet line pressure to the common high-pressure steam header pressure.

steam pressure reduction: opportunities and issues

Steam Pressure Reduction: Opportunities and Issues

2013-9-26 · Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler’s net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.

Boiler and Condenser Pressures - Rankine Cycle

2020-3-25 · The process of superheating is the only way to increase the peak temperature of the Rankine cycle (and to increase efficiency) without increasing the boiler pressure. This requires the addition of another type of heat exchanger called a superheater , which produces the superheated steam .

What is a boiler furnace pressure? - Quora

Boiler furnace pressure is the negative draft maintained by the induced draft fan to ensure the proper flue gas flow throughout its path. Negative pressure in boiler furnace also restrict the flow of flame and flue gas from furnace to atmosphere.
