Oil-fired and gas-fired boilers are the most widely used boilers at present. The two main branches of oil-fired and gas-fired boilers are oil-fired and gas-fired steam boilers and oil-fired and gas-fired hot water boilers. Oil-fired and gas-fired steam boilers mainly provide steam for industry, while oil-fired and gas-fired hot water boilers are mainly used in heating and domestic water. Usually, WNS and SZS oil-gas boilers are used. Today, the editor of ZOZEN Boiler Plant will talk about the difference between WNS type Gas/oil fired boiler and ZSZ type Gas/oil fired boiler.
WNS Gas/oil fired boiler
WNS means that the main body of the boiler is horizontal internal combustion type (code: WN), and the combustion equipment is chamber combustion furnace (code: S). WNS oil-gas fast-loading boiler is mainly composed of boiler body, connecting flue, burner, steam-water system, instrument, energy-saving device, condenser and so on. When Gas/oil fired boiler fast-loading boilers use fuel oil, light oil and heavy oil can be used as raw materials, and light diesel oil is generally used as fuel; when gas is used, gas, natural gas and liquefied gas can be generally used as fuel, and natural gas is mostly used as raw materials.

10.5MW: WNS10.5-1.0/65/55-Y (Q)
14MW: WNS14-1.6/130/70-Y (Q)
SZS Type Oil/gas fired Boiler
SZS Gas/oil fired boiler is a double drum (code number first S) vertical chamber (code number Z) combustion furnace (code number last S). It is a "D" type fast assembling water pipe boiler. It consists of upper and lower drums, membrane water wall, convective tube bundles, energy-saving devices and condensers. After the fuel is burned in the furnace, the flue gas is discharged into the chimney through convective tube bundles and waste heat recovery devices. In addition to the implementation of the national coal-fired boiler reform policy, this series of boilers will play a very important role in the future application of thermal energy equipment.

SZS type Gas/oil fired steam boiler:
6 tons: SZS6-1.25/220-Y (Q), SZS6-2.5-Y (Q)
10 tons: SZS10-1.25/300-Y (Q), SZS10-1.25-Y (Q), SZS10-2.5-Y (Q)
15 tons: SZS15-1.25-Y (Q)
20 tons: SZS20-1.25-Q, SZS20-1.6-Y (Q), SZS20-2.5-Y (Q)
SZS Gas/oil fired hot water boiler:
58MW: SZS58-1.6/130/70-Q
WNS and SZS type oil-fired and gas-fired boilers have their own advantages, but they are not conflicting in use. But in terms of capacity, SZS gas-fired boilers are much larger, so their applicability will indeed be wider. The most commendable is the "D" structure of SZS gas-steam boiler, which occupies small space, has large internal space and saves time and effort in operation. As an industrial equipment, SZS gas-steam boiler takes the advantages of the boiler into account.
