The pressure penalty makes HP boilers consume more fuel per steam than LP boilers, thus HP boilers are less fuel-efficient. This is compensated by the increased space and resource (iron) efficiency of HP boilers per unit power. A small LP boiler consumes 10.8 HU/cycle at full heat, while a small HP boiler consumes 12.8 HU/cycle (19% more).

ChatResidential Steam Boiler Basics - The Spruce
The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.
ChatBoiler Deaerator Working Principle - Boilersinfo
Deaerator feed water pump location Location : Boiler feed water pump takes suction from DA Storage tank. some of the saturated water can be flash into steam due to suction pressure, which may cause cavitation Problem in BFW Pump.

ChatSteam and Condensate - A basic overview of a steam system
The steam hits the plates, and any drops of moisture in the steam collect on them, before draining from the bottom of the separator. Steam passes from the boiler into the steam mains. Initially the pipework is cold and heat is transferred to it from the steam.

ChatInexplicable pH drop in boiler blowdown water
In one of the waste heat recovery boilers, (operates at 180 °C), pH of the blow down water drops to 5 and even 4. The feed water is maintained around a pH of 9 and the water is treated with trisodium phosphate [paid link to product info at Amazon] along with other inhibitors. The pH of the feed water is adjusted with sodium hydroxide.
ChatMultiple steam boiler piping concept — Heating Help: The Wall
The flow of steam in the boiler is much different than typical boilers. After it moves through the port connectors, it takes a turn down the very wide end section which probably kills velocity allowing water to drop out and then hits an inclined plane which probably further drys out the steam and then reaches the exit tapping.

ChatCommon Steam Boiler Problems & How to Troubleshoot Repairs
When new water enters the tank, though heated, it's still colder than the boiler water. This temperature difference creates a reduction in steam production until the fresh water warms up. Lower production of steam can drop the pressure temporarily. A continuous feedwater system may help alleviate this problem.

Aug 13, 2015 · When the water level drops in the boiler, the first set of contacts will start a boiler feed pump and / or open a feed water valve. If the water level continues to drop, the low water cutoff will interrupt the electrical service to the burner, shutting off the burner.
ChatClosed Feed Water Boiler System Explained
A closed feed system mostly consists of a regenerative type of condenser, which allows condensation of the steam with less drop in the temperature level. Once the condensate collects in the condenser, it is extracted with the help of extraction pumps and is then circulated to the air ejector.
