Central Heating Various Types Hot Water Boiler

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.

General features of the DZL series hot water boiler: Low pressure, horizontal, industrial, coal fired, fire tube, automatic chain grate water boiler. The rated thermal power is between700kw to 14000kw.

Product advantage:

1.       Spirally corrugated tube

Function: (1) Heat transfer enhancement; (2) Improve the suppleness to avoid the tube plate cracking; (3) Clean groove itself.

 2.       Arched tube plate

Function:  (1) reduce the thermal stress of weld; (2) improve the tube plate suppleness; (3) simplify the structure and save the boiler room space.

 3.       Complete protection device

Function: deal with the situation of overpressure, over-temperature, water shortage and flameout.

 4.       Up-tube layout

Function: (1) Avoid the bulging on boiler drum; (2) Promote the water cycle (3) clean the sediment in the boiler bottom.

 5.       Airfoil flue

Function: Lower the high temperature of tube plate flue gas. And then reduce the thermal load of the boiler bottom.

 6.       The return water injector

Function: Increase the reliability of the water circulation and avoid the booster caused by the poor circulation.

1. Normal type boilers that can be put into normal 20' and 40HQ containers, will be first choice to delivery it by sea in normal container. But if boiler type is over dimension that can't be put into normal container, then we use 20' or 40' flat rack container for the boielr main part and  normal container for the other boiler accessories.

2. Shipping way is different according to customer's country. Mostly by sea. Some country by train or truck.
