Low nitrogen steam boiler
The low-nitrogen steam boiler is very clean, environmentally friendly and ultra-low emission concept. The equipment has small resistance and full corrugated furnace design during operation. It extends the radiation heating surface to a certain extent and has Excellent thermal expansion, using central symmetry, lower eccentric furnace arrangement, full wet back structure, optimized high-efficiency heat transfer thread pipe, high-speed rotating turbulent flue gas inside the pipe, high heat transfer efficiency. Using a variety of safety monitoring principles, the dual pressure controller is installed in use, the double precision high pressure gauge of the whole equipment, and multiple redundant safety guarantee passages ensure the safe and reliable operation of the boiler within the design pressure range; The explosion-proof door and the starting pressure are designed reasonably to make the boiler safe and worry-free. The entire device will be equipped with a PLC programmable digital controller, which can be automatically operated during use, one-button start-stop, and multiple safety protection measures for the device, so that group control system and Internet intelligent control can be realized, and the low-nitrogen steam boiler can be assembled. , supervision products. The furnace body design is balanced and reasonable, the occupied area is small, the investment cost is saved, the PLC controller is standard, and the 7-inch touch screen display can realize automatic operation and control the boiler operation through intelligent WIFI. The plate type two-color water level gauge is selected, which is very clear and clear. The whole equipment is resistant to high temperature, high pressure, corrosion and convenient maintenance. It is equipped with electrode water level balance tube, accurately collects water level signal, monitors fluctuation of water level in the pot, and intelligently controls real-time connection, which is safe and reliable. Large-diameter safety valve, spring full-open type, high-precision control, double protection, over-pressure immediate release, escort for safety, controlled by flameout protection device, consisting of flame monitor and control device. The ultraviolet electric eye monitors the combustion of the furnace, and unexpectedly extinguishes the fire in the furnace, and immediately signals the presence or interruption of the flame, the burner automatically stops, and the self-locking protection.
