[Jada Industry and Trade to recommend star product - ship supplies] marine boiler differs from land boilers yes, right shape, size and weight are strictly limited. For example, on a warship would rather sacrifice the boiler thermal efficiency without setting the air preheater, or even set the economizer. Structurally, the boiler should be able to adapt to the ship swing, tilt and shock sailing conditions. Marine boilers have a certain steam, water storage volume of marine boilers offer, steam-powered machinery to accommodate frequent and substantial changes in load requirements. In order to meet the light requirements of small and high mobility, universal HFO. Boiler evaporation from 10 to 200 t / h steam parameters slightly lower than the corresponding evaporation of power station boilers. Early marine boilers are riveted together with iron or copper, steam pressure does not exceed 0.2 MPa. 1850 after a fire tube boiler developed. Used on marine boiler burners and land use are also different, normal to the main burner AW Rotor [Jada Industry and Trade to recommend star product - ship supplies] marine crane components: the boom boom device , lifting column (or lifting masts), rigging and winches (or winch) and other components (see Figure derrick Figure). Jib Crane device is a device aboard a traditional marine boiler models, although many ropes, operational problems, but the structure is simple, easy to manufacture, low cost, is still widely used. Single-pole and double-pole operation with the operating system loading and unloading cargo boom wholesale marine boiler, a single lever and double lever in two ways. Single lever is used for loading and unloading cargo a boom after boom lift cargo, pulling the lanyard boom swing together with the goods overboard or cargo hatch, and then down the goods, then revert to the original boom bit, so round trip. Every time when loading and unloading boom swing with lanyard, so inefficient, labor-intensive. Dual lever with two boom, one placed over the cargo hatch, the other extending outboard marine boilers, two boom with a lanyard attached to a working position. Two Crane boom with cable is connected to a hook on. As long as were close, put two cable landing, you can unload the cargo from the ship to the dock, or the goods loaded onto the ship from the pier. Dual lever handling efficiency is higher than single lever operation, labor intensity is also lighter.
