Understanding the proper start-up procedure for a biomass boiler dust collector can help prevent clogging of dust collection filter bags and extend the life of your dust collector. Let's review the proper start-up procedure for a new matter boiler dust collector and a dust collector with a new filter bag installed.
Before starting the start-up procedure of the biomass boiler dust collector, be sure to check whether your equipment is correctly installed with the dust removal filter bag and the operation of related auxiliary equipment. Where possible, a dust collector leak test should also be performed to check for dust leakage due to worn bags or improperly installed dust bags.
Be sure to turn off the power when inspecting the equipment and perform lockout, tagout, or other safety procedures as required by rotary valves, screw conveyors, and fans. To ensure that personnel work in a safe environment.
Before the initial operation of the biomass boiler dust collector, the filter bag should be pre-coated for protection
The first step is to form an initial protective dust cake on the dust removal filter bag. This is also known as pre-coating, which can be done using lime, fly ash, or a specially developed powdered material. It is the most important thing to try to ensure the dryness of the dust removal filter bag during the operation of the biomass boiler dust collector to ensure that the dust collector maintains the optimal level during the service life of the dust removal filter bag.
The biomass boiler dust collector is pre-coated with a layer of dust cake on the dust bag before shipment to prevent the dust from impacting the new filter bag at high speed and penetrating deep into the fibers and causing damage. This trapped dust may remain permanently, resulting in an increased pressure drop over the life of the dust collection filter bag. In fact, some oily or sticky dust must also be protected in advance, otherwise the dust bag will be clogged and cannot be cleaned, which is what we often call "paste bag". In extreme cases, a blockage during start-up can damage your filter bags immediately, wasting your time and money.
However, the highest collection efficiency can only be achieved with needle felt filter bags after sufficient dust cake has formed on the dust removal filter bags. Therefore, it is a good idea to pre-coat the new collector to achieve the desired level of dust collection efficiency before the biomass boiler dust collector starts up.
