Boilers are one of the most used units for both heat generation plants and industry systems. Their operation is subjected to different working loads maintenance requirements. Exploitation experience points out critical boiler zones where failures break downs typically occur. This paper analyzes in hot water fire-tube boiler. Experimental procedure was performed on model this type boilers its el...

<span>The purpose of this article is to describe the automation developed by means a programmable logic controller for burner fire tube boiler, in order improve efficiency process generating steam quantified through percentage oxygen generated. The implementation was under control strategy based on use servomotors that allow gradually open or close solenoid valves dose amount air and fuel...

As a major utility system in industry, boilers consume a large portion of the total energy and costs. Significant reduction of boiler cost operation can be gained through improvements in efficiency. In accomplishing such a goal, an adequate dynamic model that comprehensively reflects boiler characteristics is required. This paper outlines the idea of developing a mathematical model of a water-t...

The product of corrosion in the feed water system transported into the boiler and gets deposited on the internal surface of waterwall tubes. Proper treatment of boiler feedwater effectively protects against corrosion of feedwater heaters, economizers, and deaerators. It leads to overheating and on-load corrosion and ultimately tube failure.. Heat is transferred through a thin layer of superheat...
