New iPad 3: all the latest details

The new iPad launch kicked off at 10am PT/6pm GMT on Wednesday 7 March.

Browse back through our new iPad launch liveblog - or read on for a roundup of all the new iPad announcements.

Before talking about the new iPad, Apple's Tim Cook unveiled anupdated Apple TV box, bringing 1080p video streaming to the device which has a release date of 16 March and a price of $99. We've got the lowdown in our Apple TV: what you need to know post.

But it's the new iPad that grabbed the headlines:

New iPad 'better than Xbox 360 and PS3'
Whoah. The new iPad has a better screen resolution and more memory than both the Xbox 360 and the PS3? But those aren't exactly new consoles, are they?

Below are the rumours that we reported on before the new iPad was revealed.

The web was teeming with rumours about the new iPad 3 / iPad HD processor, cameras and display, so we gathered together as many details as we can on its possible specifications ahead of the launch.

Of course, some of these can be taken with a pinch of salt, but there's definite patterns occurring and we'd say the final iPad 3 release won't be that far removed from many of these rumours.

It's time to place your bets, what do you think the iPad 3 / iPad HD will bring? But wait, what's this - Sky Bet has pulled its iPad 3 betting after certain trends occurred: "If the money is correct, then the new hardware will definitely not have a new carbon fibre casing, will not be called the iPad 2S and will have 128GB of storage!".

Steam Power – Water Cycle In Boilers

Steam power - water cycle In steam boilers

Steam boiler at a power plant

High purity water for steam boilers
Power generation plants vary widely in size but most power plants share the same requirements for pure water. Raw water enters the power generation plant and is purified through several stages of filtration and demineralization.

This continuous stream of purified waterbecomes the steam boiler feed water. The boiler generates steam that drives the turbines to generate electricity. Some of the steam is also used to preheat the high purity boiler feed water. Ultimately, the steam is collected as condensate, mixed with pure make-up water, preheated and recirculated as steam boiler feed water.

Unfortunately, high purity water is corrosive to steam boiler and condensate systems. In addition, leaks in the system can add unwanted chemicals that increase corrosion potential. For example, in the condenser, raw cooling water can leak into pure water.

To counter these effects, trace level corrosion inhibitors and oxygen scavengers are typically added to the steam boiler feed water to reduce these risks. Effective chemical treatment of the boiler feed water is critical to maintaining the steam boiler and condensate systems and protecting the capital investment of the power generation facility.

Rather than determining corrosion occurrence over a period of time using an outdated technique, corrosion can now be monitored like any other process variable (i.e., pressure, flow, level, temperature, pH) by the power plant operator.

Steam condensate reclamation  Steam is used in almost all industrial boilers. Steam generated in the boiler plant is transferred to the various facilities in different pressure ranges. As energy is consumed from the steam, condensate is formed, and returned to the steam boiler plant for reuse. Steam in the boiler plant is produced from water of very high purity.

Steam condensate application challenge
Steam condenstate is collected and returned back to the boiler. It needs to be re-treated as it often acquires particulates that will cause scaling, pitting, or corrosion of the boiler tubes. Unless this condition is corrected, the steam boiler will need to be rebuilt, with extensive downtime and high costs. 

Steam condensate application solution
Depending on the size and type of steam boiler, CorrTran MV corrosion monitoringshould be installed in a location that is most susceptible to corrosion. CorrTran MV evaluates both general and localized (pitting) corrosion, as well as conductivity, in the same industrialized transmitter housing.
