Abstract
A self-regulating exhaust gas boiler intended for the recovery of thermal energy from the exhaust gases of diesel engines or the like, has a steam/water cylinder acting as the water and steam space. There is a convection part acting as the vaporizer and being fitted in the vertical orientation between the steam/water cylinder and a lower cylinder, or the like, and connected to it. There is at least one downcomer interconnecting the steam/water cylinder and the lower cylinder, or the like. At least one valve or corresponding device regulates the amount of water and the water level in the convection part is mounted between the steam/water cylinder and the lower cylinder, or the like, preferably in the lower section of the downcomer. The preferably vertically disposed pipes of the convection part are partly filled with water, the power of the exhaust gas boiler being regulated by adjusting the water level in the convection part by means of a valve on the basis of the different heat transfer properties of water, a water-steam mixture, and steam. The valve can be continuously regulated and/or of the open/shut type. The pipe or pipes connecting the convection part to the steam/water cylinder can penetrate the mantle of the steam/water cylinder at a point above the highest permitted steam/water cylinder water level.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
