Accurate understanding of boiler heating surface
Once a customer wanted to buy a 4 ton natural gas boiler, they got in touch with us and wanted to know the price of the boiler. We finally provided our customers with a solution for the WNS4-1.25-Q boiler model. After calculation, the price of such a complete boiler was around US$50,000. These include boiler body costs, boiler parts costs (Boiler feed pump, Steam header, Softened water equipment, Axial flow fan, etc.), burner costs, shipping costs, etc.
Hot water presentation of fire tube boiler and cast iron boilers understand the need of demineralized water: boiler, which is there are many types, such as one of the hot water boiler, steam boiler and so on these. However, due to the limited length of the article, therefore, it will be for one to be familiar with and understand, so that we can ensure the quality and effectiveness of learning, and will not cause confusion, thus, the emergence of various problems in the use of the boiler. 1. The alcohol-based fuel hot water boiler, which compared with a gas boiler, which is lower running costs? Alcohol-based fuel hot water boiler, which is a hot water boiler, if it is compared with a gas boiler, then, is the running costs of alcohol-based fuel hot water boiler, is lower. Because this kind of hot water boiler is a liquid alcohol as fuel, alcohol-based and uses the combustion burner, in order to ensure good combustion. 2. Why hot water boiler, be sure to use softened water? Hot water boiler specific reasons for the use of demineralized water, because it does not have a scale in the course, so, there are security risks can be avoided boilers, thereby, avoid danger or accident. Therefore, the general in hot water boiler, there will be water softening equipment. If not, then the scale inhibitor is added in a boiler, to achieve the above object.
Wuhan Port District Social Welfare Institute (apartments for the elderly) is invested by the government pension services, with a total construction area of 38,000 square meters, 532 beds, mainly adopt destitute persons, social support on behalf of the elderly. Hope to provide welfare to the elderly year-round 24-hour hot water, the original presentation of fire tube boiler equipment can not meet this demand, therefore, require additional purchase orphanage hot water boiler. After much investigation, in cooperation with the welfare determined fast boiler, provides three integrally condensing gas hot water boiler (WNS1.4-1.0 / 95/70-Y.Q) by a fast boiler.
This type of boiler is known as an exhaust-gas boiler although it belongs to the Fire Tube boiler family as the exhaust gases are fed through tubes surrounded by water. For a variety of reasons only between 5-10% of the energy in the exhaust gases is recovered in the exhaust gas boiler and the working pressures are generally below 7 bar(g).Get a Quote
Fire-tube boiler - Wikipedia. 2019-4-23 · A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.Get a Quote
The fire-tube boilers covered a steam production range of 1-20 t/hr at pressures from 10 to 20 bar. Fuels include heavy fuel oil (HFO), Sasol gas, paraffin and coal. The survey covers a total of 85 fire-tube boilers inspected over a four year period (1998-2001).Get a Quote

1. Water tube. 2. Fire tube. In water tube boilers, water circulates through the tubes and hot products of combustion flow over these tubes. In fire tube boiler the hot products of combustion pass through the tubes, which are surrounded, by water. Fire tube boilers have low initial cost, and are more compacts. ButGet a Quote
PowerPoint Presentation: It is well design of a Vertical multitubular fire tube boiler Improvement over the simple vertical boiler as it provides greater heating surface. Total heating surface area is about 10-25 times the grate area Efficiency 70-75% Ranges from 1mGet a Quote
Nov 19, 2013 · Fire-Tube Boilers. Since, in this example, the gases pass through the shell two times before exiting, this boiler is called a two-pass boiler. Due to their efficiency and reliability, fire-tube, or shell, boilers are suitable for steam-intensive industries and continuous or batch operation.Get a Quote
2. Fire tube & water tube boiler: 2. Fire tube & water tube boiler In the fire tube boiler the hot gases are inside the tubes & the water surrounds in the tube. ex. Cochran, locomotive etc. In the water tube boiler the water is inside the tube & the hot gases are surround them. ex. StirlingGet a Quote
Mar 10, 2016 · Lancashire is a horizontal, stationary fire tube boiler. This boiler is invented by Sir William Fairbairn in the year 1844.The flue gases flows through the fire tube, situated inside the boiler shell, so it is a fire tube boiler. This boiler generatenlow pressure steam. It a internally fired boiler because the furnace is placed inside the boiler.Get a Quote
Ther e are two main types of boiler Fire tube boilers and Water tube boilers. Fire tube boilers are those boilers in which fire or flue gases are inside of the tubes and water is on the shell side. Fire Tube Boilers are low capacity low-pressure boilers usually used for heating, processor to produce hot water.Get a Quote
Open system: a system that does not return the condensate. Fire Tube Boilers The combustion gases pass inside boiler tubes, and heat is transferred to water on the shell side. Water Tube Boilers Boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces.Get a Quote
