1. The increasingly powerful engines required more boilers with economisers and superheaters. 2. The Lancashire boiler was patented in 1844, and the economiser in 1845. 3. The efficiency of steam-raising is increased by a Green's economiser . 4. While in the Ministry of Finance, Tyagi earned a reputation as a strict economiser . 5. They were fitted with economisers and natural draught, working at a pressure of 160 psi. 6. Above the tube banks a single flat spiral tube was used as an economiser or feedwater heater. 7. Some preserved stationary steam engine sites still have their Green's economisers although usually they are not used. 8. This concept refers mainly to devices such as internal heat exchangers, independent subcooling cascades, economisers or boosters. 9. The engine needed more space and the engine house, boiler house and economiser were external to the main mill. 10. The HP cylinders had Corliss valves; they were steamed at 120psi, by four Lancashire boilers, An economiser was used.
