When should the filter of the furnace blower be cleaned?
Thread Content
Dear colleagues, I would like to ask you when to clean the filter of the furnace blower? When the filter is dirty, what impact will it have on the combustion of the first-stage furnace? What changes will occur to each parameter? If you are a technician, under what circumstances will you ask the staff to clean the filter? What should you pay attention to when removing the filter?
When to clean the filter? 1.PICA-103 (blower outlet pressure) is low 2.PRCA-19 (101-B) furnace negative pressure is low 3.ARCRA-8 (oxygen content in one stage of the furnace) is low. When the filter is removed, PRCA-19 will increase. The central control should pay attention to the negative pressure of the first stage furnace and the negative pressure of the auxiliary boiler, and adjust the damper to keep it normal. After the filter is removed, the oxygen content of the furnace will improve and the blower outlet pressure will increase.
