How does a water tube boiler work?
How A Water Tube Boiler Works. water tube boiler runs off of water tubes that are heated externally by fire. The tubes connect to a steam drum and a mud drum, and steam is produced in the upper drum. The water in the tubes creates steam directly, instead of tubes heating water as is the case in a fire tube boiler.
How do you start a fire tube boiler?
Start filling with soft water. Manually inject boiler water treatment chemicals including oxygen scavenger chemicals, so that the chemicals are added with the fill water. Once full to the operating level, open the fuel system and fire the boiler. Carefully bring the pressure up to 10-15 PSIG, with the vent valve open.
What is fire tube boiler with example?
Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water. The examples of the fire tube boiler are the simple vertical, Cochran, Lancashire, Cornish, Locomotive, Scotch marine, and Velcon boiler.
How are water tube boilers fired?
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. Here, saturated steam is drawn off the top of the drum.
What is difference between water tube boiler and fire tube boiler?
The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam.
What is meant by fire tube and water tube boiler?
: a boiler in which water surrounds the tubes through which hot gases pass from the furnace to the stack.
How do you turn on a boiler?
Turn the control knob to the “On” position once the pilot stays lit. Put the control access panel back on the boiler. Use the screws you removed earlier if applicable. Turn on the current to the boiler at the breaker box and then turn on the boiler power.
Which type of fuel is used in fire tube boiler?
Fire tube boilers can use fuel oil, gas or solid fuel in their operations.
How do fire tube and water tube boilers differ?
The main difference between Fire Tube and Water Tube Boiler is that In Fire Tube Boiler, hot flue gases pass through tubes and water surrounds them, and In Water, Tube Boiler water passes through tubes and hot flue gasses is surround them.
What are the difference between fire tube boiler and water tube boiler?
Which fuel is mostly used in fire tube boiler *?
C. The most common type of Exhaust Gas Boiler (EGB) used on ships are water tube boilers. In water tube type of arrangement, the water passes through tube stack, which is arranged in the path of exhaust gas inside the exhaust gas trunking of the main engine.
What is the operation of fire tube boiler?
Operation of fire tube boiler is as simple as its construction. In fire tube boiler, the fuel is burnt inside a furnace. The hot gases produced in the furnace then passes through the fire tubes. The fire tubes are immersed in water inside the main vessel of the boiler.
What happens if water flashes in a fire tube boiler?
When water flashes into steam its volume increases tremendously. This can result in a disastrous explosion. It is imperative that maximum care is exercised in the operation and maintenance of the fire tube boiler. This includes annual boiler inspections of the waterside and fireside of the boiler.
Why is the steam drum in a fire tube boiler under pressure?
In a fire tube boiler, the steam drum is always under pressure, so there may be a chance of huge explosion which resulting to severe accident. Electrical4U is dedicated to the teaching and sharing of all things related to electrical and electronics engineering.
How is the water fed into the boiler?
The water is fed into the boiler through the feed water inlet. As the steam and water is stored is the same vessel, it is quite difficult to produce very high pressure steam from.
