Title:
再生式空気予熱器の汚れ測定方法及び洗浄効果評価方法
Document Type and Number:
Japanese Patent JP7047313
Kind Code:
B2
Abstract:
To provide a dirtiness measurement method for regenerative air preheater capable of quantitatively measuring dirtiness of an element in a regenerative air preheater.SOLUTION: A regenerative air preheater is configured to transmit heat of exhaust gas flowing in an exhaust gas flow passage 17, to air flowing in air flow passages 17, 18, by an element 12. A method for measuring dirtiness of an element 12 in the regenerative air preheater comprises: radiating light, emitted from a light emitter 30, from one side of an upstream side and downstream side of the element 12 toward the other side; measuring a light reception amount at a light receiver 40 arranged on the other side; and based on the measurement value, measuring degree of dirtiness of the element 12.SELECTED DRAWING: Figure 1
