What is the difference between mounting and accessories?
Mountings are installed from simple working and control of a boiler. Accessories are installed to amplify the efficiency of a boiler. eg. Water level, indicator, Pressure gauge.
What is the function of mountings?
Function: To put off the fire in the furnace of the boiler when the level of water in the boiler falls to an unsafe limit and thus avoids the explosion which may place due to overheating of the furnace plate.
What are the different accessories and mountings of steam generator?
The various boiler mountings and accessories that are used in steam boilers are water level indicator, pressure gauge, safety valves, stop valve; blow off Valve, feed check valve, fusible plug, air pre-heater, super heater, economiser and feed pump.
Is pressure gauge a boiler mounting?
Pressure Gauge (Bourdon Pressure Gauge): The function of the pressure gauge is to measure the pressure of steam inside the boiler. The gauge is usually mounted on the front top of the shell or drum such that it should be clearly visible to the operator. It consists of a Bourdon spring tube (B) of bronze metal.

What is Babcock and Wilcox boiler?
Babcock And Wilcox Boiler is a stationary water tube boiler. It consists of the steam-water drum. a short tube connects the steam water drum with the uptake header and down header as shown in the figure. A mud box is equipped with each down space header and the mud collected, is removed.
What are boiler auxiliaries?
Auxiliary boiler means any fuel-fired combustion equipment designed primarily to produce steam for uses other than propulsion, including, but not limited to, heating of residual fuel and liquid cargo, heating of water for crew and passengers, powering steam turbine discharge pumps, freshwater generation, and space …
What is Draught in boiler?
The difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage of a boiler is termed as draft. Draft can also be referred to as the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow.
What is the function of boiler mountings?
What is whistle valve in boiler?
11) Whistle valve: If there is a provision for the steam whistle in the ship, then steam is supplied directly from the boiler through a small bore type non-return valve known as whistle valve. 12) Low-Level alarm: This is a device used to initiate audible warning at low water level condition.
What is boiler mounting?
The boiler mountings are fittings which are mounted on the boiler for its proper functioning. Mountings are water level indicator, safety valve, pressure gauge, etc. It may be noted that a boiler cannot function safely without the mountings.
What is null point in boiler?
In nearshore, shoaling waters, each particle-size of sediment should hypothetically have a null point, where there is no net movement of the particle landward or seaward.

What is PA fan in boiler?
Primary Air Fans: Primary air fans or PA fans are high-pressure fans, used in the boiler power plants to supply the air for transportation of coal directly from the pulverizer to the furnace. PA fans give positive pressure upstream of the coal pulverizer and handle relatively clean air.
Why FD fan is used in boiler?
The primary function of Forced Draft Fans is to supply air for combustion in steam boilers. FD Fans create air pressure mechanically in the combustion chamber of a boiler. One of the most preferred ways of accumulating more energy through combustion with solid fuels is through fluidized bed combustion.
