Sime Darby Jabor Palm Oil Mill Testimonial
Client Background
This boiler was experiencing very serious performance issues due to fire tube blockage which resulted in an increased back pressure within the furnace. There are two type of fuel used: –
- Palm Fibre – The blockage occurred after only 14 hours in operation.
- Palm Kernel Shell – The blockage occurred after only 36 hours in operation.
The Solution
Primasonics requested detailed information relating to the process and issues experienced along with Dimensional drawings of the Boiler in question. This data confirmed that the main problem experienced was a blockage at the inlet of fire tubes where accumulated flying-ash covered the fire tube inlets resulting in an increased pressure differential leading to a forced shutdown.
Primasonics utilized this information requested and specified that an SAH-75 Hz Primasonics acoustic cleaner curved model as the best solution to prevent the flying-ash from accumulating at the fire tube inlet.
The Result
The SAH75-C was installed as per Primasonics specific recommendations and set to sound periodically during normal Boiler operation. This frequent periodic sounding cycle continuously removes the material and prevents the blockage from forming eliminating the unplanned shutdowns. Photographs outlining the before and after installation are included below.
