A vertical fire-tube boiler is a vertical boiler where the heating surface is composed of multiple small fire-tubes, arranged vertically. Circulation became efficient and made easy be attachment of getaway tube. Gas, Gasoline and Diesel oil can all be used depending on selection of burners.

Water tube type boiler with membrane wall system is designed to keep the wall under saturated steam temperature by minimizing radiant heat loss and to maximize the efficiency of heat by a pressed combustion System.

Using waste heat generated in the waste incineration, it needs no extra fuel cost. As the smoke tube boiler, it is easy to clean and repair by good design and excellent arrangement of tube. Having 4 cornered arrangements and cleaning space, it is a clean matter to water tube typed 3drum waste heat recovery boiler.

Fire Tube is designed as spiral type to cope with thermal expansion which features high safety and high heat absorption rate. Special design and spiral fire tube offers doubled heat transmission coefficient and lower temperature of exhaust gas by 50~80 C then other boilers.

The rear combustion chamber of wet type has no loss of heat. Its smoke tube is designed as spiral type to comply with thermal expansion, which features high safety and high heat absorption rate. High heat absorption rate per unit area approves it to be a very efficient boiler.

It is an innovative boiler using heat transfer fluid to raise high temperature safety with a low pressure in a factory requiring high pressure; it can control temperature precisely with a fully automated system; it can save equipment cost as well as maintenance by achieving maximized productivity from high efficiency, minimizing fuel cast, high safety and semi-permanent life.

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapor in the exhaust gases and so recovering its latent heat of vaporization, which would otherwise have been wasted.
