COOLING TOWER INTRODUCTION: Cooling towers are a very important part of many chemical plants. The primary task of a cooling tower is to reject heat into the atmosphere. They represent a relatively inexpensive and dependable means of removing low-grade heat from cooling water. The make-up water source is used to replenish water lost to evaporation. Hot water from heat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units

Petersburg Cooling Tower Auxiliary Power Usage with VFD’s/ Control Strategy Michael J Smith – IPL Engineering & Project Management Abstract--The temperature control strategy for the cooling tower fans involves two automatic modes of operation as well as provisions for manual operation. Both modes will provide sequencing for starting/stopping each of the 14-250hp‚ 480vac fans that have been made available for automatic control. Auxiliary power savings on the 3MVA‚ 4160vac tower load can be

Chapter 16: Energy Management and Audit in Best Exports 16.1 What Is Energy? Energy is the ability to do work and work is the transfer of energy from one form to another. In practical terms‚ energy is what we use to manipulate the world around us‚ whether by exciting our muscles‚ by using electricity‚ or by using mechanical devices such as automobiles. Energy comes in different forms - heat (thermal)‚ light (radiant)‚ mechanical‚ electrical‚ chemical‚ and nuclear energy. 16.2 Definition

Geothermal Power Generating Systems There are several types of geothermal power generating plants. There is the single-flash‚ double-flash‚ dry-steam and binary cycle. These power plants can be converted into more advanced geothermal converting systems like hybrid single flash and double flash sytems‚ hybrid flash-binary systems‚ hybrid fossil-geothermal systems‚ hot dry rock (enhanced geothermal systems)‚ Power plants for hypersalline brines‚ etc.. This paper will be focusing on Single-flash steam

An open letter to our community: Many of us are aware of the risks of lead - based paint in older homes‚ gas leaks‚ contaminated water and all other chemicals with their contaminating affects on our health and our family’ s health and safety. Less known is just how close these contaminates can be hiding - even in our own backyard. I am a very happy resident living the American Dream in the Country Place suburban community located in Old Bridge‚ NJ. We have always considered this neighborhood

They lacked security for the cooling towers which without could cause the whole plant to come unstable. So there for I’m going to explain how easy it would be to execute an attack on them. I would research online and off line on how to make a simple bomb and I would make a few of them. After making them I would I simply hide them in my car as they do not 100 % search my personal car when coming though the main gate in which the parking lot faces the main cooling tower that without the main the second

Fresh Water Cooling System Introduction Although there is an abundance of free sea water available‚ marine diesel engines do not use it directly to keep the hottest parts of the engine cool. This is because of the corrosion which would be caused in the cooling water spaces‚ and the salts which would be deposited on the cooling surfaces interfering with the heat flow. Instead‚ the water circulated around the engine is fresh water which is then itself cooled using sea water. This fresh water is

Construction of The Eiffel Tower Introduction The Eiffel Tower is a freestanding framework tower (lattice tower) located on the Champ de Mars in Paris‚ France. It was named after it’s Chief Designer/Engineer Alexandre Gustave Eiffel and is the most-visited paid monument in the world with several millions ascending each year. Why was the tower built? The plan to build a tower 300 meters high was conceived as part of preparations for the World Exhibition Fair‚ which would be held in 1889
