Boilers that use solid fuel as a heat source, such as Municipal Solid Waste (MSW) incineration power plants, use a soot blower, a device to remove dust adhering to the heat transfer tubes. With the recent deregulation of electric power, there is a demand for stabilization of power generation capacity and the introduction of steamless soot blowers that do not consume steam for dust removal is required. In response, Mitsubishi Heavy Industries, Ltd. has developed a detonation soot blower that removes dust using the force of shock waves generated by combustion (detonation), and is promoting the introduction of this device in actual equipment such as MSW incineration plants. This report presents the features of the detonation soot blower, its functional verification through in-house testing, and examples of its application to actual plants.
