The steam generated in the boiler fills the space above the water in the partially filled boiler. Its maximum working pressure is limited by spring-loaded safety valves. It is then collected either in a perforated tube fitted above the water level or by a dome that often houses the regulator valve, or throttle, the purpose of which is to control the amount of steam leaving the boiler. The steam then either travels directly along and down a steam pipe to the engine unit or may first pass into the wet header of a superheater , the role of the latter being to improve thermal efficiency and eliminate water droplets suspended in the "saturated steam", the state in which it leaves the boiler. On leaving the superheater, the steam exits the dry header of the superheater and passes down a steam pipe, entering the steam chests adjacent to the cylinders of a reciprocating engine. Inside each steam chest is a sliding valve that distributes the steam via ports that connect the steam chest to the ends of the cylinder space. The role of the valves is twofold: admission of each fresh dose of steam, and exhaust of the used steam once it has done its work.
As promised, I wanted to update you on our recent cyber incident and where we currently stand. There has been and will continue to be an enormous amount of speculation in the media. It is important to understand that, as is often the case, things you read may very well not be true. Many people have expressed particular concern about our e-mail system. At this time, we do not believe that our e-mail system as a whole has been compromised, but the forensic review is ongoing. We are also in the process of engaging an outside firm to work with our employees to provide credit monitoring and we will be following up with those details. Meantime, continue to do the excellent work which defines this company across all departments and know that the appropriate teams are working round the clock to manage our way through this difficult period.
