Carbonized type gas furnace

2.1.11 Set Drum installed two furnaces typically include two sets of drum, a water jacket on the second floor of the drum operating plane, a water-cooled box drum in three operating plane, in addition to size and shape Different pressure, the basic principle is the same. Drum set in place should consider not interfere with other equipment, fire detection does not affect other operations, attention manholes, steam inlet, outlet, outlet, etc. plus azimuth and operating position. Drum set in place before should check out the difference between the outlet and inlet of steam, drawing reference method for determining one judgment, another way is to find a long piece about 1m flexible wire through the inspection, the outlet is very short in the lower part of the drum set while steam inlet should be above the longer centerline drum set, if there is no certainty should open manhole inspection. Also make sure when connecting the steam inlet steam drum outlet connections above device, the minimum retention level, and definitely not have down U-shape. Drum sets plus head pipe is generally connected to the lower position, that should be in normal operation the liquid level, to prevent serious water-carrying drum steam outlet. Here, again, for the use of a pressure higher than 0.1Mpa drum set, be sure to bring attention to the drum body is not allowed to make any changes or opening, due to its special equipment belonging to the pressure vessel by regulation, if need outwardly points took over the road is necessary to take out the line before making a tap. 2.1.12 stoker installation stoker general workshop overall shipments to the scene, but stoker at Bell, since the stability of the transport ship apart, so the addition of former stoker hoisting weight should be assembled at Bell, pay attention to check the pin lock nut and cotter pin, check the bell rotation is flexible, accurate welder after the lock nut to prevent loosening of the bell-off point of death. Check stoker seal around the machine is good, especially in the hinge release to check whether the gland packing has been added. Note stoker connection with gas stove graphite packing must be installed with thin cotton rope roll bar fixed to the flange bolt holes, then lifting stokers, taken to ensure that the drum valve inlet flange size and orientation method when lifting Bunker consistent interface. Taking into account the expansion between the gas stove, cylinder valve inlet and the bunker should be the active connection, the interface should be a smooth transition to prevent card coal. To prevent the increase of coal gas leak, the interface designed sand sealing device, attention must add sand, and finally add packing. 2.1.13 cleaning machine in place and the mounting structure and the number of cleaning machines vary furnace different, 2.2m diameter less gas furnace cleaning machine is a hydraulic ratchet mandrel type structure, 2.4m to 3.0m diameter gas Furnace hydraulic ratchet rod structure, 3.2m diameter above the gas stove is a hydraulic ratchet lever Sides cleaning structure. For the top structure, should allow positioning cylinder rod completely exposed, namely in the most distant trip, check with the chassis ratchet cylinder rod axis to the tangential direction, check the mounting angle according to the drawings, the piston rod completely exposed ejector pin fully engaged ratchet nest, this time pay attention to check the fuel tank can not stand the interference, try to ensure that the fuel tank in the middle of the cylinder bracket position, the pusher holder can not interfere with the ratchet, tighten the installation position of the spring should be adjusted appropriate to ensure that each run a ratchet tooth ratchet pusher pin can be fully into the nest. Rod type cleaning machine, pay attention to positioning cylinder piston rod should allow full access to the fuel tank, the rod at the most distant trip, the same lever pin socket ratchet should be fully engaged, check the fuel tank can not stand the interference, try to be in the middle position, After the angle adjustment appropriate check rod drive frame can not interfere with the ratchet, adjustment and reset the drive spring into place. For large diameter 3.2m above the gas stove, when the two sides to consider bilateral symmetry structure cleaning, cleaning machine positioning, the first side of the cleaning machine in place, then the other side of the place, it is necessary to ensure that both sides in order to ensure consistency two cylinders simultaneously, the trip switch should be placed away from the hydraulic station cleaning machine side, the throttle should be installed near the hydraulic station cleaning machine side, is connected between the high-pressure tubing and tanks. Note that no matter what kind of structure the cleaning machine, after the initial place should temporarily guarantee spot-cleaning machine will not shift on the line, confirmed start cleaning machine load operation a week there will be no problem to weld reinforcement ; another during welding, spot welding and other operations welder ground must be consistent with the application of solder, or may cause the cylinder seals, high pressure tubing and a ground component damage and may even cause electrical cabinet ground or zero line burning.
