steam boiler,gas fired steam boiler, 1.three-pass steam boiler, 2.Blow down automatically, 3.intelligent control - details see: https://www.machineto.com/wns4-yq-intelligent-digital-control-gas-fired-steam-boiler-10211840

1. Brief introduction of the oil/gas fired steam boiler :

l Advanced design:adopts the most sophisticated three returns all wet back structure,thread smoke tube structure, weld joint with high quality.

l Safe and reliable:adopts corrugated furnace lamps, multi-chain protection. Water level, steam pressure, gas pressure protection. And before leaving factory, all the boiler have been rigorous inspection and testing, including pressure tests and X-ray detection.

l Enough heating room:adopts unique design of a large combustion chamber which increases the radiation heating furnace area, reducing the size of the boiler, reducing the NOX emissions.

l High efficiency:with threaded pipe and high effective insulation materials, increasing the heat transfer and improve boiler thermal efficiency.

l PLC intelligent controller:boiler control system suitable for high temperature, high humidity environment of long-term operation.

l Meet customer’s requirement:different designs are available according to customers' specific requirement.
