A boiler installation units must comply with the standards promulgated by the state, reference GB50273 "industrial boiler installation construction and acceptance of universal norms" were. 2 should be read before the installation and use of this manual and electric control system schematic carefully. 3 Note: ① boiler installation site must have 380/50 (V / HZ), enough power capacity, operation and maintenance of adequate space (less than both the front and rear end 1.2m).. . ② boiler installation site should be dry and ventilated, meet fire condition; not near flammable and explosive materials; prohibit the installation in damp, open-air and acid, alkali and other corrosive places. ③. Boiler installation site must not have hypertension power interference sources, so as not to cause the control system malfunction. ④. Boiler installation must comply with load-bearing conditions, if installed on the building must seek permission from the construction sector. ⑤. Pumps, valves, tanks, piping installation must meet the requirements of GB / 50041's. ⑥. Boiler power line should have sufficient cross section. (Minimum cross-sectional area to see electric wiring diagram) ⑦. Boilers and boiler electrical control box enclosure should be grounded. Grounding resistance should be less than 4Ω. 3 boiler foundation: ground dust after compaction, watering flat concrete foundation thickness is determined by the design of the unit according to user units soil conditions. When the oil furnace fuel combustion gas boiler 2 million arts molten boiler, a flame of fire at the surface, after the flame surface is a high-temperature combustion products, previously unburned combustible mixture. Since the front of the flame after a large temperature gradient, and thus heat is spread forward, so that the adjacent layer is not gas temperature, the ignition temperature is reached after the formation of a new combustion surface. This song continues to flame propagation direction to the unburned gas flame propagation process is called. Perpendicular to the surface of the flame propagation speed is called the normal flame propagation speed. When the flow rate of the gas mixture in the direction of the normal component of the flame surface is higher than the flame propagation speed, you will find constantly away from the burner flame fire hole, after a certain distance is completely extinguished, this phenomenon is called off the fire. Off the fire only after conducting oil furnace is not working properly Arts molten boiler boiler 8 million, and will accumulate within the furnace and explosive gases have Ai Arts molten boiler boiler 6,000,000, H up can cause an explosion or other accident, which is burning process allowed. Therefore, people use fire off limits (off the fire caused by the minimum airflow rate) as a burner - an important indicator. When the flow rate of the gas mixture in a flame which component of the normal direction is lower than the flame propagation velocity, the flame will be mixed back along the burner pipe reverse combustion flame to shrink oil furnace combustor interior, a phenomenon known as temper . Tempering may burn burner or other accidents. The maximum flow rate caused by tempering called tempering limit Arts molten boiler boiler 8000000 | Arts boiler | boiler provided by the Hebei Arts Arts boiler limited liability company.
