Industrial boilers are divided into many different types, such as fuel and gas boilers, biomass boilers, coal-fired boilers, and thermal oil heaters; Heat transfer media can be divided into: hot water boiler and steam boiler. That first we need to know what is a water tube boiler and what is a fire tube boiler, to know the difference.
What is a water tube boiler?
Simply speaking, horizontal water tube boiler refers to a boiler with a combustion chamber and heating surface outside the boiler barrel. Water and steam flow in the tube.
What is a fire tube boiler?
Fire tube boiler is also called boiler shell boiler, after the combustion of fuel produced by the smoke in the fire tube or smoke tube flow, the fire tube or smoke tube outside the mixture of water and steam.
The difference between water tube boiler and fire tube boiler is:
1. Structure: fire tube boiler has the characteristics of compact structure, in the same output, shape and equipment weight are lower than the water tube boiler, and fire tube boiler efficiency is low, suitable for the production of small consumption of customers. The structure of water tube boiler is complicated, which is composed of boiler body and auxiliary equipment. More space is used to arrange superheater, so water tube boiler occupies a relatively large position.
2. Water quality: water tube boiler and fire tube boiler on the water quality difference between the former requirement is high, if the poor water quality on the performance of the boiler output, etc., will have a significant impact, at the same time also can make a big security hidden danger, the fire tube boiler for low water quality requirements, but in the long run the boiler scale for heat absorption, increase in fuel consumption.
3. Scope of application: water tube boiler has a wide range of pressure adaptation, which can break the pressure limit and meet the steam supply requirements above 2.5mpa.Fire tube boilers are limited by material wall thickness and pressure and are used below 2.5mpa pressure.
The difference of boiler types is mainly to meet the needs of different industries. You can learn more knowledge of boilers before you want to buy it. Welcome to consult the online customer service of our website.
