Embodiment Construction

[0012] The present invention relates generally to control systems for monitoring various operating parameters of spray control systems for gas conditioning applications. The control system monitors the flow rate of liquid through the spray nozzle. The system then processes the detected flow. In response, the system provides a signal indicative of the air pressure supplied to the nozzle. This achieves a reduction in compressed air consumption as well as energy savings in producing compressed air.

[0013] The present invention has particular applicability to various industrial fields. These include the pulp and paper industry, waste recycling, steel fabrication, environmental control and power generation. Various applications within these general areas include flue gas cooling prior to dust collection process stages such as baghouse dust collection installations. Furthermore, the invention can be used in conjunction with nitrous oxide control such as in fossil fuel consumpt...

Abstract

A control system for regulating the desired air pressure supplied to one or more spray nozzles receiving liquid and compressed air, wherein the compression supplied to the spray nozzles is adjusted based on various sensed operating parameters of the system amount of air.

Description

technical field [0001] The present invention relates generally to spray control systems and, more particularly, to spray control systems for monitoring operating conditions in industrial gas conditioning applications and for compensating for changes in the system in order to optimize the compressed air consumed by the system. Background technique [0002] Industrial production equipment usually produces hot gas or flue gas. Such flue gases generally have to be cooled in order for the production plant to function properly. In these applications, flue gases are often passed through various parts of the production equipment to provide a cooling effect. In other cases, however, additional cooling and conditioning systems must be used to generate the proper temperature. Flue gases are sometimes cooled by injecting a stream of atomized liquid into the gas flow, such as by spraying water into the gas flow in very small droplets. This acts to lower the temperature of the airflow....
