Justsen Energiteknik A/S expands its in-house produced boiler system elements range by manufacturing own bag filters.
The first phase of developing Justsen Bag Filter started in 2016. Today, there are several plants successfully running with the new bag filters, which are designed for both indoors and outdoors use, and have an internal bypass system. In 2017 M. Schack Engel A/S furniture production facility in Højer got their Justsen biomass boiler installed with a bag filter solution placed outdoors. A steel roof top is designed to protect the bag filter from the weather conditions. Whereas, 4 MW hot water Justsen boiler for Troldtekt A/S production facility in Troldhede is equipped with two-bag-filters unit placed inside the building. So far Justsen Bag Filters have been installed and commissioned in Denmark and France, and there are more on the way. Currently, there is another two-bag-filters unit being installed in a boiler plant for MSM Milling’s canola processing facility in Australia.
The bag filter is equipped with automatic bag cleaning by means of compressed air, including filter control with different pressure cleaning, as well as reduction valve and water separator. The insulated filter is built up as a square filter with in- and outlet in the top of the filter. The filter is complete with four legs and one or two fly ash extraction screw, including gear motor as standard execution. The filter is designed for shifting bags from either top or inside the filter chamber based on overall plant design and building.
As a part of boiler system service and maintenance, Justsen experts are also trained to perform a bag filter leakage test to determine whether or not there is a leakage in the installed bag filter. The test is done in three steps: 1) the filter assessment, 2) UV torch inspection, and 3) report and advice.
Justsen boiler owners now have a possibility to choose to equip their boiler system with Justsen Bag Filter in order to comply with emission requirements and contribute to clean air.
