摘要： A radiant superheater (26) arranged to hang at the upper portion of a furnace (12) of a boiler. The radiant superheater (26) is substantially planar and includes a first vertical (34) pass, a first connection pass (36), a second vertical pass (38), a third vertical pass (40), a second connection pass (42), and a fourth vertical pass (44). Each vertical pass includes an upper end and a lower end. The vertical passes are connected in series, so that steam to be superheated enters at the upper end of the first vertical pass and flows through the first vertical pass and from the lower end of the first vertical pass via the first connection pass to the lower end of the second vertical pass and through the second vertical pass and from the upper end of the second vertical pass to the upper end of the third vertical pass and through the third vertical pass and from the lower end of the third vertical pass via the second connection pass to the lower end of the fourth vertical pass and through the fourth vertical pass, to be discharged from the upper end of the fourth vertical pass. The first connection pass is arranged below the second connection pass so as to shield the second connection pass from radiation from the lower portion of the furnace.

摘要： A method of controlling a boiler plant during a switchover period from an air- combustion mode to an oxygen-combustion mode. The method includes steps of feeding fuel into a furnace of the boiler plant at a rate determined by a fuel feeding scheme, feeding air into the furnace at a rate determined by a descending air feeding scheme, feeding substantially pure oxygen into the furnace at a rate determined by an ascending oxygen feeding scheme, and recirculating flue gas into the furnace at a rate determined by an ascending flue gas recirculating scheme. The fuel feeding scheme, the air feeding scheme and the oxygen feeding scheme are such that the fuel is combusted and the flue gas containing residual oxygen is produced. Also, the fuel feeding scheme, the air feeding scheme and the oxygen feeding scheme are such that the content of residual oxygen in the flue gas is, during at least a portion of the switchover period, greater than during any of the air-combustion mode and the oxygen-combustion mode. The method makes it possible to reduce CO2 emissions and O2 consumption quickly during the short switchover period.
摘要翻译：一种在从空气燃烧模式到氧气燃烧模式的切换期间控制锅炉设备的方法。该方法包括以燃料供给方案确定的速率将燃料供给到锅炉的炉中的步骤，以由下降空气供给方案确定的速率将空气进入炉中，以基本上纯的氧气以一定的速率由上升的氧气供给方案确定，并且以烟道气再循环方案确定的速率将烟道气再循环到炉中。燃料供给方案，供气方案和供氧方式是燃料燃烧，并且产生含有残余氧气的烟道气。此外，燃料供给方案，空气供给方案和供氧方案是这样的，即在至少部分切换期间内，废气中的残余氧含量大于空气燃烧模式和氧气燃烧模式。该方法可以在短时间内快速减少二氧化碳排放量和氧气消耗。

摘要： A method of increasing the power of a carbonaceous fuel combusting boiler system. The method includes the steps of (a) feeding carbonaceous fuel (16) into a furnace (14) of the boiler plant at a fuel feeding rate, (b) feeding oxidant gas (18) into the furnace for combusting the fuel to produce exhaust gas, (c) discharging the exhaust gas from the furnace via an exhaust gas channel (20), (d) conveying a stream of feedwater from a boiler economizer (38) arranged in the exhaust gas channel to evaporating and superheating heat exchange surfaces arranged in the furnace and in the exhaust gas channel for converting the feedwater to superheated steam, (e) expanding the superheated steam in a high-pressure steam turbine (50) for generating power, (f) extracting steam (74) from the high-pressure steam turbine at a decreased rate for preheating the feedwater, (g) conveying steam from the high-pressure steam turbine at an increased rate to a reheater (36) arranged in the exhaust gas channel for generating reheated steam, (h) expanding the reheated steam in an intermediate pressure steam turbine (52) for generating power, and (i) conveying the exhaust gas in the exhaust gas channel from the reheater through a boiler economizer to a gas heater (42). The method also includes increasing the heat exchange surface area of at least one of the reheater and the boiler economizer and/ or adding a high pressure economizer downstream of the boiler economizer and upstream of the gas heater.
