Abstract
971,298. Arrangements of steam boilers. COMBUSTION ENGINEERING Inc. May 28, 1963 [June 19, 1962], No. 21269/63. Heading F4A. A method of supplying low purity steam to satsify the low purity steam requirements, e.g. for soot blowing, of a steam power plant, including a main steam generator, a turbine installation operated on a high purity steam cycle by said main steam generator, and an auxiliary steam generator operable during startup of said main steam generator to operate the auxiliaries thereof, comprises introducing low purity feed water into said auxiliary steam generator when the same is in a non-firing condition during normal operation of said main steam generator and turbine installation, extracting high purity steam from said high purity steam cycle, passing said high purity steam in heat exchange relation with said low purity feed water, thereby transforming said feed water into steam, and passing the socreated low purity steam to satisfy said low purity steam requirements. A main steam generator 10 comprises a combustion chamber 16, an evaporator 17, a superheater 18, a reheater 19 and burners 20, and an auxiliary steam generator 12 comprises a combustion chamber 33, a water drum 35 and a steam drum 34 joined by heat exchange tubes 36, and a superheater 37. During start-up of the main steam generator 10, burners 38 of the auxiliary steam generator 12 operate and high purity water from a source 40 is admitted to the auxiliary generator and turned to steam. With valve 45 open and valve 50 closed, the high purity steam passes through a superheater 37 and line 46 to operate the auxiliaries 13, e.g. turbine drives and feed water heaters, of the main steam generator before passing into a condenser 24 and into the main steam circuit. When the main steam generator 10 and the associated turbine installation 11 reach their normal operating condition, valve 45 closes and valve 31 opens, steam from the main circuit then driving the auxiliaries. Firing of the burners 38 ceases, and valve 42 is actuated so that low purity feed water from a source 41 passes into the auxiliary generator. A portion of the cold reheat steam exhausted from the high pressure stage 22 of the turbine installation 11 is passed through a heat exchange vessel 47 to the water drum 35 in which low purity steam is generated for soot blowing purposes in the main generator 10. This low purity steam is superheated in the exchange vessel 47. The remaining steam from the turbine installation 11 passes through a reheat section 19 to a low pressure stage 23 and the condenser 24. A three-element flow control system 43 controls the feed water flow to the generator 12 and the water level in the drum 34.
