A comparison between water tube and fire tube boilers

Feb 12, 2018 · Fire tube boilers. In a fire tube or shell boiler, the hot combustion gases produced by the burner are passed through small tubes arranged in a pressurised cylindrical drum and surrounded by water. Heat energy is transferred to the water which is heated up until it becomes steam.

What are Boilers and Their Types? - Engineering Choice

Shell and tube boilers are also referred to as fire tube or smoke tube boilers. Fire-tube boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. Fire-tube boilers, typically have a lower initial cost, are more fuel-efficient, and are easier to operate.

Q1: What is the boiler efficiency?

1) Heating surface of the water tube is over heated, and then brings about the factor of water damage. 2) The heating transfer is prevented, and then brings about the low boiler efficiency. 3) The flow area of the water tube is decreased, and then brings about bad circulation.

Difference Between Fire Tube Boiler and Water Tube Boiler

Aug 12, 2020 · In a hydronic system, both fire-tube and water-tube boilers can be viable solutions. A water-tube can be a great selection on a retrofit job with limited space for a large boiler. A primary secondary set up is very easy to integrate with an existing system. A fire-tube can also be the better solution if you are designing a system with only one set of variable speed pumps in mind.

Choosing The Right Boiler: Watertube vs. Firetube - Boiler

Jun 13, 2013 · Boilers come in all different types, sizes, and shapes and are classified by configuration of the furnace, or firesides, and the watertubes, or water holding volume. The two main boiler types consist of firetube and watertube boilers, and deciding which of the two will best fit your process needs is not as easy as it may seem. It is like comparing

Firetube vs Watertube Boilers: a Comparison

Fire tubeor "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam cir-culates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm2.

The Differences Between Water Tube Boilers and Fire Tube

Mar 16, 2017 · Water tube boilers have better efficiency ratings and generally drive lower fuel costs. They do cost more up front, however, and cleaning the unit can be difficult because of its design. Fire tube boilers, on the other hand, are relatively less expensive, smaller in size and easier to clean though they have pressure limitations. When choosing

Thermal Design of Economizer for Waste Heat Recovery Boiler

improving the efficiency of a high pressure steam boiler is to install an economizer on the boiler. Typically, on a high pressure water tube boiler, the efficiency improvement with an economizer is 2 to 4%, depending on firing rate. On a high pressure fire tube boiler, the improvement is 2 to 3.5%, depending on boiler size and firing rate.

Water Tube Boiler - Definition, Components, Working

A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.
