Why is My Boiler Making a Strange Noise - Causes & How to Fix

Find the filling loop (flexible silver cable) and make sure both ends are tight or you may have an internal filling key but its the same principle. Open bath valves or turn your internal filling key to allow cold water into the system, this will repressurise the system. When the gauge reaches 1.5 bar close both valves.

Boiler filling loop: the 2 different kinds and how to use

Aug 07, 2018 · The boiler filling loop is a boiler component which provides a temporary connection to the mains in order to fill and pressurise the central heating system with water. It also allows the system to be topped up where necessary, for example, after bleeding radiators. Regularly topping up the system usually indicates a leak, and doing so will damage the system in the long-term.

Steam locomotive components - Wikipedia

Early American locomotives had bar frames, made from steel bar; in the 20th century they usually had cast steel frames or, in the final decades of steam locomotive design, a cast steel locomotive bed a one-piece steel casting for the entire locomotive frame, cylinders, valve chests, steam pipes, and smokebox saddle, all as a single component.

Steam Accumulators | Spirax Sarco

In Figure 3.22.14, the boiler is steaming at its normal design pressure, for example 10 bar, and the steam passes to variable loads which require not more than, for example 5 bar. Pressure reducing valve A is reducing pressure between the boiler header and the distribution main in the plant, responding to the pressure sensed in the 5 bar line.

Alternative water-tube boiler layouts. The following layouts work on the same principles as other water-tube boilers, and are available with capacities from 5 000 kg/h to 180 000 kg/h. Longitudinal drum boiler. The longitudinal drum boiler was the original type of water-tube boiler that operated on the thermo-siphon principle (see Figure 3.3.5).

What is Boiler Draught? Types, Classification, Advantages

May 12, 2020 · Boiler draught is defined as the difference between absolute gas pressure at any point in a flow passage and the ambient (same elevation) atmospheric pressure.Draught is achieved a small pressure difference which causes the flow of air or gas to take place. It

Injector - Wikipedia

An injector is a system of ducting and nozzles used to direct the flow of a high-pressure fluid in such a way that a lower pressure fluid is entrained in the jet and carried through a duct to a region of higher pressure. It is a fluid-dynamic pump with no moving parts, excepting a valve to control inlet flow. A steam injector is a typical application of the principle used to deliver cold water

Working of Boiler Explanation, Parts, Working Principle

Working Principle of a Boiler. It is simple to understand the boiler working. To understand it, let us have a look on it. Low-Pressure Boiler: The maximum pressure is of 15-20 bar and is used for the purpose of heating. High-Pressure Boiler: This boiler has a maximum pressure of more than 80 bars.

Boiler Mountings And Their Function - Complete List

Aug 05, 2018 · The working of a boiler is similar to boiling water in a pan or cooker at home. The boiler is a closed vessel where water is boiled off the heat received from the furnace. The steam produced is stored in steam drum at 60 bar for heavy industries and steam ships; while at 7 to 15 bar for motorized ships and other application.
