SZS series gas-fired (oil-fired) hot water boiler

SZS series oil and gas fired boiler is a packaged water tube boiler with double drums and D-type layout. Burning oil and gas, this boiler has lower emission of carbon dioxide, NOx (nitrous oxide), SOx (sulfur dioxide) than coal fuels. As an ideal environmental protection product, it obtains approval from government and factories with high efficiency, low energy consumption and less pollution.

High degree of automation, safe and stable operation

(a) The layout of SZS series boiler has a large heating surface area, the design of gas space is big enough to ensure the stability of the boiler parameters;
(b) Adopts internationally renowned brand of totally automatic burner ,which optimize the fuel and combustion air ratio, greatly improving the combustion of the furnace;
(c) With full set of safety protection device, thus automatic safety operation can be guaranteed , which reduce boiler operation maintenance cost.

High steam quality, superheated steam is available

SZS is equipped with two-stage steam separation device, which is conducive to the separation of steam and water gravity and improve the quality of steam; It can be saturated steam can also be superheated steam.
