Types of boilers, Fire tube, water tube and combination

Even the most sophisticated high-temperature and pressure watertube boiler can be simply described as pressure parts (drums, headers, and steel tubes) which contain high-pressure steam and water. The tube surface transfers heat to the water from a fuel being combusted in a controlled manner outside of the tube …

function of the convection tube spacing which dictates the boiler pressure vessel diameter. It is also related to one of the design standards that has developed over time for firetube boilers. That design standard is five square feet of heat transfer surface per boiler horse power. That is the equivalent of O. 145 square feet per pound of

Jan 09, 2019 · Fire tube boilers can use fuel oil, gas or solid fuel in their operations. Working: The ignition process occurs in the pipe, then the heat generated is delivered directly into the boiler containing water. The size and construction of the boiler affect the capacity and pressure produced by the boiler…

Why are fire-tube boilers not suitable for high pressures

Fire tube boilers are those in which the products of combustion pass through the tubes and water lies around the outside of tubes. These boilers operate at moderate pressure (16-20bar) and more suitable to generate 3-8 tons of steam per hour which is used in process heating.

Why Water Tube Generate More Steam and Pressure Than Fire

Nov 01, 2017 · Take a three­pass fire tube steam boiler with a capacity of 5000 kg of steam per hour and a operating pressure of 10 bar for example. The Figure below equations shows a standard three pass fire tube steam boiler system used as a template for our engineering team's design. Conduction through piping to the water is described in the equation

The Only Boiler Maintenance Checklist You Will Ever Need

It is because hot-water heaters are usually so reliable that many consider them benign. But consider this: If you could capture all the energy released when a 30-gallon home hot-water tank flashes into explosive failure at 332°F, you would have enough force to send the average car (weighing 2,500 pounds) to a height of nearly 125 feet – or more than the height of a 14-story apartment

Fire Tube Boiler Design Calculation--ZBG

Higher pressure systems operate from 15psig to 350psig. Although firetube boilers are available in ratings up to 85,000 pounds of steam per hour (lb/hr), they are generally used when the steam pressure is under 150psig and boiler capacity is 25,000 lb/hr. Watetube boilers are used for larger, higher pressure, superheated steam applications.

A Boiler: The Explosive Potential of a Bomb

Introduction. Fire tube boilers, also known as smoke tube boilers, are the most common type of industrial boiler employed today. Compared to water tube boilers, they are much more suitable for smaller plant applications because they can better cope with sudden high demand steam fluctuations.. Combustion occurs within a furnace with the exhaust gasses (flue-gasses) passing through a series of

Aug 30, 2019 · The water tube boiler generates more steam of high pressure whereas a fire tube boiler generates steam of low pressure. We will discuss the fire tube boiler, different types of firetube boilers, defects, and uses. Fire Tube Boiler. In Fire Tube Boilers, hot flue gases will be flown inside the tube and these tubes are surrounded by water. These are the low-pressure boiler which cannot generate much heat compared to water tube boilers.

Firetube vs. Watertube Comparison - Johnston Boiler

The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes offer a far greater heating surface area for the
