Our company's SZS oil-fired gas boiler is an environmentally friendly boiler developed on the basis of our company's years of experience in producing oil-fired gas boilers and through years of cooperation with domestic famous scientific research units and colleges.On the basis of the company's existing oil and gas boiler operation data, the latest generation of high-efficiency, energy-saving and environmentally friendly oil-fired gas condensing boilers have been developed.Using natural gas and then the flue gas contains a large amount of water vapor, the latent heat of vaporization is recovered, and the boiler efficiency is increased to more than 100%.A variety of products of the company have been awarded the title of "Energy Efficiency Star" by the Ministry of Industry and Information Technology, and a number of national patents have been obtained, and the technical level is leading in the industry.

Technical advantages

Unique structural design

The double-drum vertical D-type arrangement is adopted, and the important pressure components such as the drum are not directly protected by high-temperature flame radiation and erosion.

The boiler adopts the design concept of large furnace, which burns completely, is not easy to deposit carbon, has the characteristics of high efficiency and sufficient output, and low nitrogen oxide emission.

The boiler adopts a self-supporting type structure, saving steel frame and space.

The economizer and condenser adopt the spiral finned tube type to enhance heat transfer, and the countercurrent arrangement has good heat transfer performance.

The condenser is made of special ND steel, which has good corrosion resistance to condensed water and greatly improves the service life.

Reasonable flue structure, smoke box hydrophobic structure, condensed water is easy to discharge, collect and process.

Large-scale assembly and supply, reducing the workload of on-site installation.

The economizer and condenser can be placed on the upper part of the boiler according to the site conditions.

Energy saving and environmental protection

The boiler adopts the design idea of large furnace to reduce the heat load of the furnace volume. With professional burners, the NOx emission is as low as <30mg/Nm³.

99% of the composition of natural gas is methane (CH4), which contains a large amount of hydrogen (H). The flue gas after combustion contains a large amount of water vapor. According to theoretical calculations, the proportion of water vapor in the flue gas is about 18%. If the water vapor is condensed into water and the latent heat of vaporization is recovered, about 5% of the heat is recovered, and the boiler efficiency can be increased to > 100%.
