TYPES OF BOILERS : Fire-tube boiler A fire-tube boiler is a type of boiler in which hot gases from a fire pass 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.

The following are the types of boilers most commonly used in industrial and commercial settings, along with some terms to know when trying to differentiate between different boiler styles and figuring out their ideal uses. Fire-Tube A fire tube boiler setup directs heated gases into a number of tubes that run through a water-filled chamber.
Get a QuoteBoiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler." Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler.

A boiler is a steel pressure vessel in which water under pressure is converted into steam by the application of combustion. In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads.

Solution
1, due to the decrease of the atmospheric pressure, the fuel combustion speed slower burn time becomes longer, increasing the dissociation rate of the carbon dioxide, chemical incomplete combustion heat loss is increased. Solution to this problem is to appropriately increase the furnace volume, increased fuel residence time in the furnace.
2, no influence of the atmospheric pressure drop pairs exiled heat transfer coefficient of the heating surface, but decreases of Flame cause radiation heat transfer coefficient is reduced, so that the overall heat transfer coefficient is reduced. While reducing the radiation heat transfer coefficient caused by furnace exit gas temperature rise increases the convective heat transfer temperature difference, but to ensure that the exhaust gas temperature rises to a certain extent without excessive levels of convection heating surface area of the boiler should be appropriate increase.
3, low-altitude wind pressure effect on the smoke characteristics of a large gas-fired boilers, gas boilers running in the plateau region, the burner selection must be a revision in its air volume and pressure, ensure that the output power and boiler burner output.
October 23, the 13th China International Wine & Beverage Processing Technology and Equipment Exhibition (referred to CBB2018) kicked off in Shanghai. Fang Group combine fast wine, the actual needs of users in the field of beverage industry, using its own investment to build more efficient how many types of fire tube boiler test center platform, continuous investment test and adjust them, to bring the latest "Core Europe" series boilers and condensate recovery system solutions exhibition debut.
The smoke exhaust heating unit not only increases the how many types of fire tube boiler load, but also finds that the smoke exhaust temperature is increased to a certain extent. In operation, it is found that the flue gas temperature of this kind of boiler is lower, the exhaust temperature is only about 120 ℃ at 70% load, and 103 ℃ at 150% overload. Therefore, you can not install economizer. Although the actual exhaust temperature is lower than the standard, there is no corrosion of flue gas to flue gas and fan after operation. In addition to the low exhaust temperature in the overloading operation of the boiler with threaded flue gas tube, the exhaust temperature of other type boilers under reasonable air distribution is lower when the overloading operation is carried out. For example, the exhaust temperature of SZL4.2-95/70 hot water boiler is about 208C ~ 210C at 70% load and 210 ℃ ~ 213C when overloading is 140% or so, for example, the temperature of exhaust gas is about 208C ~ 210C in 70% operation of the hot water boiler with door produced by a certain factory. When the exhaust temperature of some hot water boilers exceeds 150 ℃ due to design reasons and overloading, a economizer should be installed to reduce the exhaust temperature and avoid the fan running beyond the design temperature (200 ℃).
