Aug 22, 2018 · In a fire tube boiler, the main boiler vessel is under pressure, so if this vessel is burst there will be a possibility of major accident due to this explosion. Types of Fire Tube Boiler According to the location of furnace there are two types of fire tube boiler and these are external furnace and internal furnace type.
Dec 07, 2016 · Water Tube Boilers. Unlike fire tube boiler, where the hot gas is circulated through tubes to heat water in a tank, water tube boilers involve running water through tubes surrounded by a heated tank. These types of boiler are generally considered safer than fire tube designs and typically require less frequent maintenance.
Aug 24, 1976 · Usually in boilers of this type the hot gas flows downwardly through the tubes; in which case the space above the upper tube sheet constitutes a manifold to distribute the incoming hot gas to all of the firetubes. As this gas flows down through the firetubes, it is cooled by indirect heat exchange with the water in the boiler.
In a firetube boiler, the flue gas travels through the tubes, which are surrounded by hot water. Firetube boilers are typically designed with either three or four sets of tubes (three- or four-pass boilers). Every set of tubes that the flue gas travels through is considered a “pass”. Boilers designed for three-passes have the stack at the
Dec 09, 2015 · Exhaust gas boiler (EGB or EGE) or economiser described in this article is a smoke tube boiler with steam space, used for heat recovery from main engine exhaust gas. An illustration of the boiler is shown in figure below. The exhaust gas boiler is designed as a vertical boiler with a cylindrical shell surrounding the boiler tubes and water drum
Whatever the type of fuel being fired, all high pressure boilers are bound to have a tube failure during the course of their working life. Did you know that a single tube failure in a 500 MW boiler requiring four days of repair work can result in a loss of more than $1,000,000 apart from the generation loss?
In water tube boilers thermal fatigue can occur when there is frequent wetting of a hot surface such as is caused by an ill placed and leaking valve dripping internally into a hot steam line. Such failure of a steam line could have very serious consequences. Thermal fatigue cracks can be similar to corrosion fatigue and the two are often confused.
Internal header baffles can be installed in the headers of the entire line of hot water boilers to adequately baffle the flow rate through the boiler to the required design system flow rate. Our 6-10 pass staggered tube design allows for maximum heat absorption of the products of combustion.

Typical electric process heating applications include fuel gas heaters, fuel oil heaters, glycol reboilers, TEG heaters, MEG heaters and water heaters.
The flue gas ‘down-draft’ design forces hot gases through the lower part of the boiler where cooler water normally accumulates. Features to Simplify Maintenance A three-section rear cover arrangement provides complete accessibility of all firetubes and the furnace.
with firetubes in the water phase, and questions it. It explains why it is so wrong to do this, and why it is so much better to locate treater firetubes in oil. HEATER TREATER DESIGN: FIRETUBES IN WATER It’s safe to say that nearly all heater treaters in 1960 had firetubes in the water phase. By then there were over 400,000 treaters in operation.
Lattner Boiler Company. 2014-4-10·convective heat transfer firetubes.

Oct 28, 2013 · Water Tube Boilers – In contrast to fire tube boilers; a water tube boiler uses the water rather than the heat which is contained inside of a system of interconnected tubes. The heat moves around the tubes, thereby heating the water within the tubes and gradually transforming it into steam.

Aug 22, 2018 · 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. As the hot gases are passed through these tubes, the heat energy of the gasses is transferred to the water surrounds them.
Jul 27, 2016 · The boiler works on the same principle as the water is heated in a closed vessel and due to heating, the water changes into steam. This steam steam possesses high pressure kinetic energy.The boiler contains water. The water is heated to its boiling temperature by the use of heat from the furnace.
