When Did ZHONGYUAN Boiler Works First Begin Making Boilers?

SBW started in 1930 as a high quality welding company. During the 30s and 40s, small firetube boilers were fabricated. In 1954 the first SBW boiler registered with the National Board was put into service.

What is a Firetube Boiler?

A firetube boiler is a boiler in which hot gases of combustion pass through the boiler tubes and water surrounds these tubes to absorb heat.

What are Good Applications for Firetube Boilers?

There are many applications for firetube boilers, some are: Heating, Sterilization, Laundries, Food Processing, Co-generation, Heat Recycling, Cleaning, Petroleum Extraction, and any other process that may require steam or hot water.

Can a Firetube Boiler React Quickly to Load Changes?

A firetube boiler can react very quickly to load changes due to the fact that it has a large volume of stored energy in the form of hot water and steam.

What is the Expected Life of a Firetube Boiler?

The expected life of a firetube boiler is 25 years or more, depending on how well the boiler is maintained. Many firetube boilers currently in operation are well over 25 years old and still making steam and hot water.

What Types of Firetube Boilers Does ZHONGYUAN Boiler Works, Inc. Manufacture?

SBW manufactures 2-pass and 3-pass dryback boilers as well as a full line of 3-pass and 4-pass wetback boilers.

What is a Dryback Boiler and How Does it Compare to a Wetback Boiler?

A dryback boiler has a rear wall that is lined with refractory, a wetback boiler has a rear wall that is jacketed by water. Because of this fact, wetback boilers typically boast higher efficiencies than dryback boilers as the heat from combustion goes directly into heating water instead of refractory. Wetback boilers are also more forgiving with load changes as the reversal chamber of the boiler is totally submerged in water creating an even heat transfer on the intermediate tube sheet to furnace joint.

What is the Size Range of ZHONGYUAN Boilers?

ZHONGYUAN Boilers are manufactured from 10 BoHP to 2,500 BoHP.
