The double-drum gas steam boiler adopts two leading technologies in the world’s low-nitrogen combustion field, staged combustion and FGR flue gas recirculation, which can reduce NOX emissions to less than 26 mg/m3. It is 1/6 of the current national general standard, and not only fully meets the current stringent requirements of low nitrogen emission standards (30 mg/m3). It has reached the advanced level of low-nitrogen emission combustion technology. The horizontal double drum boiler has high safety and a thermal efficiency of up to 98%. And equipped with the intelligent boiler Internet of Things system, this furnace not only achieves ultra-low nitrogen emissions, but also greatly saves energy, becoming the customer’s first choice.
The dual-drum steam boiler is suitable for a wide range of fuels, and can use high, medium and low calorific value gas fuels. The boiler layout is flexible, and the parameters are various (saturation, overheating). Gas-fired steam boilers are complex to manufacture and have a long installation period. The performance of the boiler is not only related to the manufacturing quality, but also to the installation quality. The furnace adopts a modular water-cooled wall structure, and the boiler adopts an airtight inner protective plate with a fully enclosed welded structure, and the furnace wall has a good seal.
The horizontal double drum boiler adopts high thermal resistance material as the heat insulation layer, which has good heat preservation performance. The SZS series steam boiler has a surplus heating surface and a large enough steam and water space to ensure the stability of the boiler parameters. It adopts a fully automatic burner with high combustion efficiency and has the functions of ignition program control and overpressure and flameout protection. The boiler adopts a water spray desuperheater, which has sensitive temperature adjustment and a large temperature adjustment range.
The fuel of this type of gas fired boiler is sprayed (atomized) from the burner, ignited, suspended and burned in the furnace, washed through the rear smoke window to flush the second return convection flue, and then discharged through the chimney through the economizer arranged on the left side of the boiler atmosphere. The flue gas of the steam boiler scours the convection tube bundle horizontally, with good heat transfer effect and low metal consumption.
The gas-fired steam boiler has large water capacity and adopts natural circulation, and the hydrodynamic power of the heating surface is safe and reliable. The anti-corrosion and anti-scaling measures adopted by the SZS series boilers ensure that the furnace body will not corrode and prolong the service life. The front and rear smoke box doors of the boiler are easy to open and close, and the disassembly is flexible, which is convenient for boiler maintenance and maintenance.
The unique pulse water level detection circuit structure of the horizontal double drum boiler has reliable performance. The whole adopts centrifugal glass wool multi-layer heat preservation, low heat loss, adopts t1.5 cold-rolled steel plate to bend the edge, inlaid outsourcing, overall spraying, compact and beautiful appearance.
