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.
The following is a list of Lexus vehicles, including past and present production models, as well as concept vehicles and limited editions. Model generations are ordered by year of introduction. This list dates back to the start of production in 1989 for the 1990 model year, when Lexus was founded as the luxury division of Toyota Motor ...
