Doble steam-car boiler: donkey boiler: A donkey boiler is used to supply non-essential steam to a ship for 'hotel' services such as heating or lighting when the main boilers are not in steam, for example, when in port. [3] Donkey boilers were also used by the last sailing ships for working winches and anchor capstans. See also auxiliary boiler.
In 1869, Brooks leased the Dunkirk shops facility from the NY&E and formed the Brooks Locomotive Works. [1] The new company officially opened on November 13, 1869. [2] The company's first steam locomotive was completed the following month as part of an order for the NY&E, the company's first customer.
In 1914 the Forges at Chantiers de France fitted armor on three cars at the request of a Royal Naval Air Service squadron in Dunkirk. One of these, a 50 hp Rolls-Royce, was thus the first Rolls-Royce armored car. The armor was 6mm boiler plate, so could only protect against a rifle bullet from a distance of 600 yards (550 m) or more. [5]
The Pressure Equipment Directive (PED) 2014/68/EU (formerly 97/23/EC) [1] of the EU sets out the standards for the design and fabrication of pressure equipment ("pressure equipment" means steam boilers, pressure vessels, piping, safety valves and other components and assemblies subject to pressure loading) generally over one liter in volume and having a maximum pressure more than 0.5 bar gauge.
In the United States, many boilermakers are employed in repairing, repiping, and re-tubing commercial steam and hot water boilers used for heating and domestic hot water in commercial buildings and multi-family dwellings. [1] Sometimes these boilers are referred to as pressure vessels. Generally, a pressure vessel is a storage tank or vessel ...
Three-drum boiler, casing removed. Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary ...
Tube cleaning is the process whereby the boiler tubes of steam locomotives are cleaned out, removing soot and ash in order to ensure the effective generation of the draught for the fire. This was often done with steam lances or compressed air and accompanied by brushing as required.
They are particularly visible in the Leader boiler, as the firebox is dry-walled, rather than water-jacketed. Czechoslovak State Railways 498.1 featured thermic siphons in the firebox Thermic siphons (alt. thermic syphons ) are heat-exchanging elements in the firebox or combustion chamber of some steam boiler and steam locomotive designs.
