Product Description
WNS Series High Efficiency Oil Fired Steam Boiler
The product model is Wns, a horizontal internal combustion of three
-cycle gas (gas) with a fast charge integrated wet -back boilers.
and condenser. The boiler is equipped with a perfectly automatic
control and a safety system for the realization of automatic
control, alarm and deactivation of the lowest water level,
automatic boiler ignition, automatic setting of the firepower of
the furnace fire protection to ensure safe operation. Installation
of boilers.
Brief Introduction of Boiler Operating Conditions
The boiler can operate permanently under 80%100% working
conditions.Under the 100% nominal load, the boiler operating
parameters are: temperature of supply water 20C, the nominal
working pressure 1.25MPA, and ten tons of steam 193.4C can be
produced in one hour.If the fuel is natural gas, we would calculate
Heat efficiency is 98.96%, exhaust temperature is 48.93 degrees
Celsius, and fuel consumption is 754.78Nm3 /h (the product is used
for one day). Low gas calorific value (>36.36MJ /Nm3)
