This is a new, innovative and professional service offered to original equipment manufacturers, epc contractors, plant owners and financial institutions to protect them against probable failure or underperformance of fluidized bed equipment. Although the epc contractors take total responsibility of the plant ensuring that all components of plant meet their performance guarantee offered by the vendors, it has been observed that sometime after the guarantee period, in many cases, the gasifier either gave less than desired generation or poorer quality of the product. In most cases, since these incidents occurred well after the contractual performance tests, the owner could not claim compensation from the supplier. Only in limited cases these resulted in protracted legal procedures with minimal effect on the profitability of the plant. Gri, as a specialist in the field, offers an alternative to this potential loss of revenue by acting on behalf of the plant owner in thoroughly checking the design of the gasifier of torrefaction plant every step along the way to ensure that necessary steps are taken in the design and construction to avoid potential boiler failure in the future.
