WNS series coal fired furnace Introduction
The coal fired furnace has the functions of high and low water level alarm, low water level interlocking protection and overpressure interlocking protection. In order to effectively monitor and control the water level and pressure, the coal fired furnace is equipped with a water level gauge, an electrode water level control alarm, a pressure gauge and a pressure controller to make the boiler high. Low water level alarm / low water level interlock protection and steam pressure overpressure interlock protection, coal fired furnace automatic ignition, burner fire automatic regulation and extinguishing protection, to ensure the safe operation of the automatic water boiler.
Mode of combustion: fuel is ejected from the burner, ignited by a high-pressure electron ignition, and burned under a slightly barotropic pressure in the furnace. The high-temperature flue gas after burning embers turns 180 °from the rear smoke chamber to the second return, Turn 180 °from the front smoke box into the energy saver and condenser from the chimney into the atmosphere.
The front cigarette box adopts the integral double-door setting, the double-layer seal of the smokebox door, this form integrity is good, beautiful, generous, the opening is also very light when overhaul.
The chimney height shall be 8 meters, and the user shall determine the actual height according to the requirements of the environmental impact statement approved by the local environmental protection department, but not less than 8 meters.
Our oil/gas fired boilers can be divided into DHS series angle tube boiler,SZS water tube boilers and WNS fire tube boilers depending on the medium inside the tubes. With multiple pressure designs, the water tube boilers can meet the steam supply requirements of 2.5MPa or above. The fire tube boilers, on the contrary, are intended for use at pressures below 2.5 MPa. Fire tube boilers usually have a capacity of below 20t/h, while water tube ones of 20t/h or more as capacity expansion is possible.
The three series are designed with large furnaces, the thermal efficiency is over 98%, and the NOx emissions are as low as 30mg/Nm3. The front and rear smoke boxes are all equipped with a unique sealing structure to ensure that the smoke box does not leak smoke. At the same time, it has the characteristics of fully automatic and safe operation.
