A gas-fired boiler is a device that absorbs heat from the combustion of fuel and converts water into certain parameters (such as pressure, temperature, etc.). Gas fired steam boilers are composed of boiler body, burner, electric control cabinet, feed water pump and pipe valve instrument. The unit is equipped with imported burners, and the body adopts the mature structure form of horizontal internal combustion three-return wet back type. The fuel is ejected from the burner at a high speed through pressure atomization and burns in the furnace chamber at a micro positive pressure.
The high temperature flue gas after combustion radiates heat exchange in the furnace and turns into the second return flue pipe to the front flue gas box, then turns 180 degrees into the third return flue pipe, and is discharged into the atmosphere through the rear flue box and the condenser.
This series of gas fired boilers abandon the traditional idea of “equal velocity” design for the second and third return journey on the arrangement of convective heat transfer pipe area. A new idea of “equal resistance” is adopted to arrange the convective heat transfer surface. The traditional idea of determining the diameter of furnace pipe by flame diameter is broken through in the design of furnace pipe. The large corrugated furnace tank structure is adopted to greatly increase the radiation heat transfer area and reduce NOX emissions.
The gas fired steam boilers have threaded flue gas pipe technology is applied in the convective heat exchanger zone, and the boiler efficiency is over 96.2%, which greatly improves the boiler efficiency. The smoke box adopts double sealing small smoke room structure, eliminate the leakage of smoke, and facilitate the maintenance of users. Aluminum silicate fiber felt is used for insulation, with good insulation effect. As we have done a lot of work in combustion and heat transfer, we have adopted some new structures and technologies, which greatly reduce the volume of the product, reduce the room space and reduce the weight.
This series of boilers adopt movable double sealing structure in front and rear smoke box, which is convenient for inspecting, repairing and cleaning inside the boiler. The boiler can be installed quickly as a whole, running without vibration, and installation is convenient and fast. The boiler computer controller can automatically record the time and reason of failure, which is convenient for maintenance personnel.
