CHAPTER TWO: Boiler Operation Maintenance & Safety Study …

2.1.3 Water-tube boilers: • Water-tube boilers have water running through the tubes and fire or gases of combustion surrounding the tubes. The water tubes are connected into a steam drum at the top and a mud drum at the bottom. The fire is in the Combustion chamber. The boiler design can also be

Boiler Gauges, how to read the temperature & pressure

Heating boiler gauges: this article describes the combination pressure & temperature gauge found on most hydronic (hot water) heating systems. The boiler gauge gives helpful temperature or pressure readings that tell us if the boiler is operating normally. The same pressure and temperature readings at a boiler can help diagnose problems such as TP valve leaks, cold radiators, and even boiler

Technical Guidance Document: Steam Purity for Turbine

Drum boiler or HRSG (drum-type) Boiler in which steam (generated in heated evaporator tubes) is separated from water in an unheated horizontal pressure vessel (drum). The liquid phase is recirculated to the evaporator. Feedwater Water that is pumped into a boiler or HRSG to balance the steam production

Boilers - University of Alabama

Water-Tube Boiler (1867) A water-tube boiler is one in which the products of combustion pass around the outside and heat tubes containing the water. The water tube diameter is much smaller than the shell diameter of a fire-tube boiler, so much higher pressures can be obtained, well over 2000 psi. The furnace and boiler tube area must be

Industrial boiler technology for beginners

boiler of this type, filled with water and ready for function, can weigh as much as 165 tons, which corresponds to the weight of 120 VW Golfs. Hot water or steam boilers are relatively similar in design (Figure). The boiler pressure vessel is a horizontal, cylindrical tube closed at both sides with an end plate and insulated all around.

Kettle Reboiler - an overview | ScienceDirect Topics

The pressure of steam used for heating is limited to 1 barg (15 psig), corresponding to a temperature of 120°C, with the steam saturated rather than superheated. If the flow to the vaporizer is excessive, the heating is insufficient or the heat transfer surfaces are fouled, the chlorine vapor may lose superheat, liquid droplets may be
