preheat
An air preheater is any device designed to heat air before another process (for example, combustion in a boiler With the primary objective of increasing the thermal efficiency of the process. They may be used alone or to replace a recuperative heat system or to replace a steam coil.
In particular, this article describes the combustion air preheaters used in large boilers found in thermal power stations producing electric power from e.g. fossil fuels, biomass or waste. For instance, as the Ljungström air preheater has been attributed worldwide fuel savings estimated to 4,960,000,000 tons of oil, "few inventions have been as successful in saving fuel as the Ljungström Air Preheater", marked as the 44th International Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers.The purpose of the air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by reducing the useful heat lost in the flue gas. As a consequence, the flue gases are also conveyed to the flue gas stack (or chimney) at a lower temperature, allowing simplified design of the conveyance system and the flue gas stack. It also allows control over the temperature of gases leaving the stack (to meet emissions regulations, for example). It is installed between the economizer and chimney.
Does the bug affect cabin pre-heat, battery pre-heat or both?
I decided to do a battery pre-heat this morning. Started it 90 minutes before departure; app said it was on. Looked again 30 minutes before departure and app said it was off.
Hey.
Had my SE SR since September 2022. Cabin preheating has worked most of the time, but now it’s refusing which given this week’s weather is beyond frustrating.
Is the issue with cabin preheating not working when the car is plugged in but not charging still a thing?
Also noticed when the...
Since having to upgrade the Smart app. When I use the front windscreen defrosting option. It just blows cold air.
Does anyone know how to change this to blow hot air?
So, I am interested to hear from the collective...
Have any of you suffered from issues when trying to Pre-Heat?
I can Pre-Heat the cabin when the car is plugged in and charging, but crucially I cannot Pre-Heat when the car is not plugged in? I get a failure to execute. Code 47. I have the...
