摘要： PROBLEM TO BE SOLVED: To provide a stoker furnace recirculated exhaust gas supply control method and a stoker furnace capable of performing a substantial reduction of NOx concentration at a furnace outlet without increasing CO concentration.SOLUTION: A recirculated exhaust gas fed from a front side is supplied from a front side ceiling wall rearward and a recirculated exhaust gas fed from a rear side is supplied from a rear wall or a rear side ceiling wall forward, respectively. A distribution of temperature in a combustion chamber is measured to calculate at which position a combustion position on a fire grade is located in a forward or rearward direction with respect to a prescribed reference range. A distribution ratio between the recirculated exhaust gas from the front side and the recirculated exhaust gas from the rear side is changed according to the cases, i.e. a case in which the combustion position is located at a forward position, a case in which the combustion position is located at a rearward position and a case in which the combustion position is located within the reference range.

摘要：【課題】排ガスのNOx濃度変化を素早く予測する。【解決手段】焼却炉1は、複数の火格子により搬送される廃棄物の搬送経路の各位置において廃棄物に対して一次空気を供給して廃棄物を燃焼させる一次燃焼室2と、一次燃焼室2で発生した未燃ガスに二次空気を供給して未燃ガスを燃焼させる二次燃焼室3と、二次燃焼室3から排出される排ガスを大気に導く排出経路4とを備える。一次空気の流量、一次空気の温度、一次燃焼室2内の温度、二次空気の流量、二次燃焼室3内の温度および二次燃焼室3内の酸素濃度のうちの2つ以上を含む対象パラメータ群の値がパラメータ値取得ユニット5により取得される。NOx濃度予測部101では、対象パラメータ群の値に基づいて排ガスのNOx濃度の予測値が取得される。これにより、排ガスのNOx濃度変化を素早く予測することが可能となる。【選択図】図1

摘要： PROBLEM TO BE SOLVED: To provide a waste incineration facility that can heat-recover both sensible heat and latent heat of vapor included in an exhaust gas and can generate electricity efficiently concerning the waste incineration facility which incinerates wastes in an incinerator or heats them in a low oxygen state in a gasifying furnace and utilizes the waste heat to generate electricity.SOLUTION: A waste incineration facility is equipped with a waste incinerator 1 or a gasifying furnace 21, a superheater 2, a dust collector 4 such as a bag filter, and a chimney 5, a latent heat recoverer 6 for recovering the latent heat of vapor included in an exhaust gas from the dust collector 4 is provided in a rear stream of the dust collector 4, and the exhaust gas after latent heat recovery is released to the air via the chimney 5. An exhaust gas roundabout line 17 for detouring a latent heat recoverer 6 is divergently provided halfway on a line 16 which supplies the latent heat recoverer 6 with the exhaust gas from the dust collector 4, and it is preferable to control a flow rate (F1) of the exhaust gas to be supplied to the latent heat recoverer 6 and a flow rate (F-F1) of the exhaust gas which detours the latent heat recoverer.
