Water cooled fully premixed vacuum boiler

SZWRS-350

The water-cooled fully premixed ultra-low nitrogen condensing vacuum hot water boiler adopts the water-cooled fully premixed combustion technology, which is controlled by a continuously variable frequency fan and a proportional gas valve linkage to accurately control the excess air coefficient and maintain full mixing of gas and air at all times, ensuring complete combustion. At the same time, the unique condensation technology of the water-cooled stainless steel finned tube circulating cooling flame of the vacuum hot water boiler's heat medium water and burner can quickly reduce the temperature at the root of the flame, making the gas burn more fully. The inverted cold flame combustion, reverse heat exchange, rapid heat transfer, and sufficient heat transfer present a blue flame state, effectively suppressing the flameSynthesis of NOX, NOX emissions under operating conditionsBelow 30 ㎎/m ³.

Seven characteristics of fully premixed low nitrogen vacuum hot water boiler

1The unique condensation heat transfer technology of the new integrated water-cooled premixed combustion full film wall structure water tube three-stage condenser water tube phase change;

2Lower exhaust temperature, less heat loss, and high thermal efficiencyextend108%；

3. Heat exchangers made of high-performance composite materials such as stainless steel have super strong resistance to condensation corrosion and anti scaling functions;

4Always operating under negative pressure, with no risk of expansion or explosion, safe and reliable;

5Water cooled fully premixed combustion technology, with stepless variable frequency fan and proportional gas valve linked control;

6Compact boiler structure, integrated design of boiler and heat exchanger, small water volume and smaller volume;

7Fully automatic intelligent control system, touch screen operation, simple and intuitive.
