    Fire protection for enclosed belt conveyor

    Regarding enclosed belt conyers used for grains transport, with capacity around 1200 or 1600 metric tons per hour, I wonder which the correct fire protection system is for these conveyors. I am referring to belt conveyors similar to the "Hi-life" conveyors of Hi-roller. Which is the NFPA recommendation?

    I can't see any industry standard recommending any specific equipment manufacturer. Please show us a link that shows this recommendation.

    "Hi-life" conveyors of Hi-roller is simply a specification for an enclosed conveyor idler system and has nothing to do with fire protection. "Hi- Life" is simply a custom specification from the manufacturer to your requirements. The belting must be a flame resistant specification and the enclosure materials along with the fire suppression system is a requirement of the local area fire protection codes. I would first have a discussion with an inspector having jurisdiction in the area of installation - get a copy of the appropriate building or industrial codes. Then hire a reputable designer / engineering firm to design your system to the appropriate codes and requirements. Make them responsible for following all applicable codes in their design.

    The NFPA refers to a handbook of reverence. So it can be referenced: the spelling difference is intended. While the consequences of fire can be very different the causes of fire are not. It is therefore amazing that fire resistant belts are not universally obligatory. Whether or not the material burden is flammable does nothing to consider the combustibility of a slipping belt etc etc.

    First read the book and make sure that your 'reputable designer/or engineering firm' has also read and understands the book. I have jumped all over those who haven't, they are quite few, but dangerous. In the final event you should ensure that the local fire service is happy with your proposed design.... some rather advanced Asian nations do this automatically: and for free. Their efforts pale in comparison to the possibilities of death or injury for one of their own personnel or the operators. At the first sign of sparks the reputable people will be rapidly applying for bankruptcy just before they apply for a new business licence.
