Heat has always been very useful to man kind. One of the basic and common ways to obtain heat is by burning combustible fuels. However, such combustion must be controlled and safe. Safety of combustion is ensured by monitoring flame. Flame is characterized by emission of wide spectrum of electromagnetic radiation starting from infra red, visible light to ultra-violet radiations. Flame is also known to generate ions in its envelope. Type of fuel and that of burner decides which one of these radiations predominate. For example; flame of coal or oil is usually very bright and yellow in color, flame of light oil like kerosene or that of hydrocarbon gas is light blue and flames of some gases may be even dull reddish. In addition to this, intensity of flame could differ widely depending on the type and size of flame. Diligent micro controls has varieties of flame sensors of different techniques & fixtures and also has flame monitors diligent flameye series suitable for these techniques as well as to substitute for most of the imported models.
Diligent flameye is also available with fixed or variable delay for flame on or flame off response. This is very useful when flame is not steady or inherently obscured by the environmental conditions; such as flare tower flame monitoring.
Diligent micro controls offers wide range of controllers for automatic control of all types of burners. Classifications of these controllers are based on type of fuel burnt, design of burner, mode of operation, technique of flame sensing, starting pre-requisite interlocks, security interlocks, etc. Diligent autocon controllers are completely solid state types and use standard and time-proven components. This ensures their continuous & reliable operation over long period even under adverse conditions of electric power and environment. Each autocon has its unique & user friendly "status & fault" display that displays status of various equipments and that of faults that leads to burner failure. This feature is very useful during commissioning and fault finding of burner. A diligent autocon controller work on 230 v +/- 10%, 50 hz, 1 phase ac supply and provides live operating commands to switch on or off various equipment related to the burner operation. Alternately, it can be made suitable for operation on 110 v or any other power supply specified by the customer. It has been our experience over past two and half decades that the time delays in the controllers should be preset in the factory rather than in the field. However, we can offer some delays as "field settable" to our new oems for their initial trials on their system and later on these can be factory set at the value specified by the oem. Diligent autocon burner controllers are designed to answer most of the requirements of combustion control as well as to substitute for most of the imported models.
Diligent autocons are housed in strong m.S. Or plastic enclosures. Interconnection with burner component is either screwable or pluggable. These are either base mounting type or door mounting type ordoor mounting type.
