A gas-fired steam boiler is a heating system that utilizes steam as a medium to transfer heat to a building or industrial process. The steam is generated in a boiler by burning natural gas or another fuel, and then circulated through pipes to radiators or other heat exchangers in the building or process. As steam travels through the pipes and radiators, it releases heat to the surrounding air or process fluids and transforms into the water in a condenser or another heat exchanger. The resulting condensed water is then returned to the boiler for reheating and to repeat the cycle.
Gas steam boilers use the new “Ultraten” technology heat exchange element—feather tube, the unique tear groove design increases the heat exchange area, strengthens the disturbance of the central flue gas, makes full use of heat, has better heat transfer efficiency, and higher energy utilization.
Fully premixed combustion technology reduces the formation of NOX. The condensate at the tail of the boiler also absorbs harmful gases in the flue gas, effectively reducing pollutant emissions, NOX<30 mg/m2, meeting the urban emission standards.
Water circulates outside the wing tube, which is not easy to scale and easy to clean. Large volume design, not only long-term operation without loss of heat transfer efficiency, but also facilitates water circulation, and it is difficult to scour the pipe wall to scale.
The steam gas boiler adopts an integrated design, and in-factory commissioning, one only needs to install water inlet and outlet pipes, chimneys, gas pipes, and pain points on site to use, saving installation and commissioning time. The water inlet and outlet are all at the rear of the furnace body, which is convenient to install and beautiful and tidy.
The Gas steam boiler adopts the classic wet back structure design, the tube plate, backplate, and simplified body of the furnace body are protected by pot water, effectively avoiding the risk of smoke leakage and local high-temperature operation, safe and worry-free, and due to mature technology, the production cycle is short. The burner is easy to operate, and it can be started automatically only by operating the switch of the boiler control cabinet; the oxygen content is monitored online to ensure its stable operation and installation.
In a typical three-pass boiler design, the combustion gases are first directed through the combustion chamber where the fuel is burned, and the hot gases are then routed through the first pass, which is made up of a set of tubes that surround the combustion. In the second pass, the hot gases flow through a second set of tubes, typically arranged in a U-shape or a similar configuration. Finally, the hot gases flow through a third set of lines in the third pass before being vented to the atmosphere through a chimney or stack. The three-pass design allows for greater heat transfer efficiency, as the hot gases are exposed to a larger surface area of the boiler tubes, which in turn heats the water more effectively. This results in a more efficient boiler that can produce more steam for a given amount of fuel.
