BDR Thermea Group has been developing hydrogen boilers for use in heating technology as a way to help decarbonise heating. In 2019, the company was the first to apply a high-efficiency hydrogen-powered [broken anchor] boiler in a real-life setting in Rozenburg, the Netherlands, together with gas grid provider Stedin, the municipality of Rotterdam, and the housing association Ressort Wonen.
Babcock-Johnson boiler: early production Johnson boilers operating at high pressures (850 psi [59 bar; 5,900 kPa]) and with water-wall ends to their furnace. [4] Babcock & Wilcox boiler; Babcock & Wilcox marine boiler; Bagnall boiler: a development of the launch boiler, with an enlarged furnace. Also known in agricultural use as the 'colonial ...
Condensing boiler manufacturers claim that up to 98% thermal efficiency can be achieved, [3] compared to 70%–80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies around 90%, which brings most brands of condensing gas boiler in to the highest available categories for energy efficiency.
Babcock & Wilcox-type boiler designs become popular in new installations. 1881 (): Alexander C. Kirk obtained the necessary high pressure boilers for the first practical installation of a triple expansion marine engine in SS Aberdeen. [21]: 106–111 1884 (): Charles Algernon Parsons develops the steam turbine. Used early on in electrical ...
They are listed in chronological order from when each model began its model year. If a model did not have continuous production, it is listed again on the model year production resumed. Concept cars and submodels are not listed unless they are themselves notable.
