How it works
SPGs are permanently attached to the outside of boilers, furnaces, cement kilns and other suitable types of equipment. The target area is cleaned by means of controlled shock pulses of detonated gases (methane and oxygen) and is a fully automatic process. These shock pulses are dispersed over a large area around the discharge tube of the SPG which dislodges ash and fouling.
The detonation frequency of SPGs can vary from 15 minutes to every 24hrs depending on the level and nature of fouling. The detonations can occur either to a pre-arranged schedule or when performance tracking indicates a requirement. As a result SPGs can increase the periods between maintenance outages and improve the overall efficiency and cost effectiveness of a plant.
