Contact SupplierSafety and reliability have been a challenge in today’s coal fired boilers at thermal power stations. FOURESS, in technical consultation with a few discerning customers have developed the perfect solution to the pressing problem of effective isolation of PF mills. This has been done with the ingenious concept of TWIN SEAL FLAP (TSF) Isolator, which guarantees 100% sealing efficiency for safe access to on-load maintenance of PF mills.
Majority of the coal fired boilers in India use guillotine gates as Isolating equipment for PF mills. This technology has become out dated owing to its ill-equipped provisions. As such, Maintenance Engineers on the site face a host of problems, some of which are as follows :
Existing guillotine gates do not use an effective sealing system. This results in leakage of gas to the downstream. High velocity coal laden gas further aggravates the leakage making it virtually impossible for maintenance personnel to take up on-load maintenance. Thus an additional blanking plate becomes essential.
The entire operational area gets polluted due to transit leakage during operation of the guillotine gate.
There is frequent failure of cylinder seals owing to heat radiation during operation.
