Abstract
141,708. Aktiebolaget Vaporackumulator. April 12, 1919, [Convention date]. Digesters.-To prevent the liquid contents of a steam-heated digester from flowing into the steam pipe when the pressure in the pipe is below that in the digester, steam, air, water or other fluid at a higher pressure than the maximum pressure on che digester is forced into the steam pipe at a point intermediate of the cut-off valve and a non- return valve. The part T of the steam pipe between the cut-off valve A and the non-return valve B is arranged vertically so as to form a liquid seal. A supply of high pressure steam or other fluid enters the top of the seal from a pipe M. The cut-off valve and the vertical part of the steam pipe are made of acid-proof metal. The high-pressure steam supplied to the seal may be taken from a steam accumulator connected to the boiler by a pipe containing a non-return valve.
