ISO9001:2008 gas boiler features:

Adopt numerical control system including automatic mode,manual mode, timing mode, error recording,password protection function,etc.Be provided with automatic blowdown system ,effectively reduce scale formation and extend the working life of the boiler.Auto-Scale alarm(Independent patent technology) & overpressure protection devices ensure safe operation of the boiler.Maintenance easy—The front smoke box adopt articulated joint which is easy to be open and makes the flue tubes cleaning get more simpler and easierSafe and reliable---before leave the factory, all the boiler have to pass series of strict tests ,especially on combustion and auto control devices to ensure the safety and relaiblity .

Applications

Fangkuai shell type gas/diesel fired steam boilers suit all industrial applications like Drugs & Pharmaceuticals Dyes Chemicals, Paper, Plywood, Agro based Industries, Food Industry, Dairy and other process industries.

Construction

All of these boilers adopt fire tubes structure that has better adaptability on water quality. The internal wet-back rear smoke gas reversing chamber, as well as the first smoke tube and second smoke tube, are all arranged for optimum flow within the horizontal cylindrical pressure vessel. Radiant and convection heat surfaces generate in tandem a rapid water circulation, which accelerates the steam bubble transport to the steam chamber. The transferred fuel heat is converted into steam quickly and without material stress through an even heat transfer. The large water chamber offers sufficient storage volume to be able to cover off even sudden peak in consumption.
