Marine boilers produce high pressure superheated steam to drive the turbines. The steam is generated by the water tubes which connect the water drum to the steam drum. Water and steam circulate through the vertical banks of tubes; the inner ones supplying the top drum and the outer ones dropping steam and water back to the water drum.
Universal steam boiler CSB Ultra-compact steam boiler producing up to 5,200 kg/h of steam, built to EN 12953 standard. The CSB excels with its high efficiency rating of up to 95.3% and its low emissions already comply with future requirements of the MCP Directive (EU) 2015/2193.
Appliance operating flue temperatures vary from appliance to appliance. An appliance flue gas temperature rise could be between 15F and 30F above the entering water tempera- ture. This will determine what flue material is needed.
SZS Gas & Oil Water Tube Boiler. SZS series oil and gas fired boiler is a packaged water tube boiler with double drums and D-type layout. Burning oil and gas, this boiler has lower emission of carbon dioxide, NOx (nitrous oxide), SOx (sulfur dioxide) than coal fuels.
The steam boiler CSB can be operated with different liquid and gaseous fuels, such as natural gas, fuel oil, biogas, and with multi-fuel firing units. Thanks to the low-NOx burner and generously dimensioned flame tube, the boiler already reliably falls below the strict EU emissions limits of the MCPD for 2025 and/or local emissions regulations.
Jan 15, 2006 · Plastic flues As condensing boilers have low flue-gas temperatures, specifiers can use plastic flues for certain applications. Boilers such as Hamworthy’s Milborne condensing wall-hung range, can safely work with a polypropylene flue.

From what I know of the properties history the boiler hasn’t moved position from where it used to be, but now that it is a condensing boiler the plume output is much more visible, plus now we are living here the boiler is actually being used.
Exhaust Gas Temperature Limits. The lowest temperature to which flue gases can be cooled depends on the type of fuel used: 250°F for natural gas, 300°F for coal and low sulphur content fuel oils, and 350°F for high sulphur fuel oils. These limits are set to prevent conden- sation and possible corrosion of the stack.

The steam that exists at the same temperature as the water from which it is formed is known as saturated steam. In other words, saturated steam exists at approximately 100°C (212°F) at atmospheric pressure. One of the main characteristics of saturated steam is that it is dry; i.e., it does not contain any water droplets.
