Hot water in boiler chamber will flow three times in horizontal tubes which provides more opportunities for hot gasses to transfer heat to the water in a boiler. However, boiler efficiency is highly affected by tube design, and not simply the number of passes. 3-pass boiler with more heat transfer time to deliver the same or higher efficiency rating.

Nearly no news reported vacuum hot water boiler explosion event. This is because phase changing vacuum hot water boiler working in the negative pressure, unlike other hot water boiler. This ZWNS series boiler capacity is from 0.5 to 6 ton per hour, basically meet hotels, schools, buildings, supermarkets hot water or heating requirements.

If you want to purchase a set of hot water boiler, you should know its capacity, pressure, temperature, fuels, etc. The basic knowledge of hot water boiler will be helpful.

Heating system is composed of three parts hot water boiler, heating line and radiator. Usually, it is a complex process to calculate heating consumption, heating pipe diameter, system pressure loss, etc.

Producing energy saving and high efficiency boiler is closely associated with boiler producers and boiler users. Who own technology of energy saving, who can gain an competitive position in boiler market competition so as to earn large profits. How to save boiler fuels cost, improve fuel efficiency is what ZBG engineers study.

This passage describes WNS series gas fired steam boiler in pasteurization used in milk processing. Pasteurization is the process of heating milk to below the boiling point to destroy microorganisms and enzymes that contribute to the reduced quality and shelf life of milk.

Take natural gas boiler as an example, we will see how to calculate the 1 ton gas boiler fuel consumption. ZBG a leading boiler manufacturer and supplier has 1 ton -130 ton natural gas fired boilers for sale!

ZBG can provide fire tube and water tube condensing boilers that mainly fire natural gas, LPG, coal gas, light oil, heavy oil, diesel, etc.

The energy saving water tube gas fired boiler designed by gas fired boiler manufacturer ZBG has higher thermal efficiency, full output, energy-saving, the thermal efficiency is up to 90%.

The two main category of steam boilers: water tube boiler and fire tube boiler are for all walks of life, of which the fire tube steam boilers are quite efficient with a relatively smaller capacity range but widely appear in middle-small companies.
