During operation, the heat exchangers of the boilers require periodic cleaning. Ash accumulated in the heat exchange part, first of all, creates aerodynamic resistance drag and significantly impairs the heat transfer process, thereby causing a drop in power and efficiency.
Cleaning the heat exchanger in manual mode requires a complete shutdown of the boiler for a certain time, which creates discomfort to heat consumers and service personnel. With installation of pneumatic cleaning, the heat exchanger is cleaned automatically without stopping the boiler. The device is a universal cleaning system, which is made in the form of receivers installed in front of the heat exchanger door. Pneumatic cleaners are installed on boilers of "M" and "M-1" series, and, at the request of the customer, they can be applied to boilers with manual loading. The number of receivers and pneumatic valves in them depends on power of the boiler, namely the size of the convective part of the heat exchanger.
