Gas water boiler natural gas fired hot water boiler WNS gas water boiler energy saving type gas water boiler

  Gas water boiler natural gas fired hot water boiler WNS gas water boiler energy saving type gas water boiler   WNS hot water WNS series which are boiler of horizontal three pass fire tube with internal combustion. New design with structure of circular furnace wet back and larger volume burning room which can enhance burning efficiency and reduce the emission of Nox. Gas with high temperature is scouring the fire tube the second and third pass in turn. Then the gas is blown into atmosphere through chimney from the back smoke chamber. It used specifically thermal insulation material to lessen the heat loss. It is easy for maintenance due to install the hole for people and hand inside to clean.   General features of WNS series boiler: 1.    horizontal , gas & oil fired , water tube, industrial and low pressure; 2.    wetback and three-backhaulstructure design; 3.    With high efficiency economizer, the thermal efficiency can reach more than 90%. 4.    The spring-loaded type explosion door ensures the boiler safety 5.    The removable smoke boxfacilitates the maintenance 6.    Internal micro positive pressure combustionreduces the low temperature corrosion. 7.    Equipped with protection devicesfor overheating, overpressure, lacking water, leak detection, flameout, etc. This ensures the boiler to operate safely and efficiently. The product advantage: 1.    Subulate furnace and corrugated furnace combination   Function: (1) Make the structure more compact; (2) improve the thermal efficiency; (3) relieve the expansion and contraction 2.    Smooth tube and spirally corrugated tube combination   The smooth tube Function: Prevent the exhaust from condensing inside the boiler to prolong its service life ;   The spirally corrugated tube Function: (1) relieve the expansion and contraction; (2) Heat transfer enhancement;; (3) clean groove by itself.   3.    The furnace sits in line with the combustion Function: (1) Make the structure more compact; (2) prolong its service life.
