Abstract

Official abstract text for this publication.

The invention provides a boiler load analysis apparatus that has a simple configuration and achieves highly accurate analysis of a boiler load. A boiler load analysis apparatus ( 10 ) includes an opening sensor ( 15 ) provided to at least one of a fuel supply line ( 45 ) and a combustion air supply line ( 50 ) of a boiler ( 40 ) and configured to measure an opening degree of at least one of a fuel flow regulating mechanism ( 47 ) configured to regulate, with the opening degree, a fuel flow in the fuel supply line ( 45 ) and a supplied air flow regulating mechanism ( 54 ) configured to regulate, with the opening degree, a supplied air flow in the combustion air supply line ( 50 ), and a load analyzer ( 20 ) configured to calculate a steam load of the boiler ( 40 ) from a measurement value of the opening sensor ( 15 ), to analyze the steam load of the boiler ( 40 ).

First claim

Opening claim text (preview).

The invention claimed is: 1. A boiler load analysis apparatus configured to analyze a steam load of a boiler, the apparatus comprising: an opening sensor provided to at least one of a fuel supply line and a combustion air supply line of the boiler and configured to measure an opening degree of at least one of a fuel flow regulating mechanism configured to regulate, with the opening degree, a fuel flow in the fuel supply line and a supplied air flow regulating mechanism configured to regulate, with the opening degree, a supplied air flow in the combustion air supply line; and a load analyzer configured to calculate the steam load of the boiler from a measurement value of the opening sensor, wherein the opening sensor is disposed at a link mechanism of at least one of the fuel flow regulating mechanism and the supplied air flow regulating mechanism and configured to detect a rotation angle of the link mechanism. 2. The boiler load analysis apparatus according to claim 1 , wherein the opening sensor is a tilt sensor fixed to the link mechanism. 3. The boiler load analysis apparatus according to claim 1 , wherein the opening sensor is disposed at an arm of the link mechanism. 4. The boiler load analysis apparatus according to claim 1 , wherein the boiler load analysis apparatus is configured not to be placed inside a duct of the boiler, but to be placed at the link mechanism from outside the boiler. 5. A boiler load analysis apparatus configured to analyze a steam load of a boiler, the apparatus comprising: an opening sensor provided to at least one of a fuel supply line and a combustion air supply line of the boiler and configured to measure an opening degree of at least one of a fuel flow regulating mechanism configured to regulate, with the opening degree, a fuel flow in the fuel supply line and a supplied air flow regulating mechanism configured to regulate, with the opening degree, a supplied air flow in the combustion air supply line; and a load analyzer configured to calculate the steam load of the boiler from a measurement value of the opening sensor, wherein the opening sensor is a clamp current sensor attached to a control signal electric cable of a drive motor of at least one of the fuel flow regulating mechanism and the supplied air flow regulating mechanism.
