BOILER STEAM AMOUNT MEASURING METHOD, BOILER LOAD ANALYZING METHOD, BOILER STEAM AMOUNT MEASURING APPARATUS, AND BOILER LOAD ANALYZING APPARATUS

摘要

PURPOSE: A method for measuring the amount of the steam of a boiler, a method for analyzing a load of the boiler, a device for measuring the amount of the steam of the boiler, and a method for analyzing the load of the boiler are provided to measure the amount of the steam changed by the minute without using a steam flow-meter with no a response delay. CONSTITUTION: A device(1) for measuring the amount of the steam of a boiler comprises a pressure difference detection member(4) and a controller(6). The pressure difference detection member measures a pressure difference between pressure at a first detection position of a can body(7) or steam outlets(3A,3B) of the steam boiler and pressure at a second detection position of the steam outlets separated downstream of the first detection position. The pressure difference is measured by making the steam of a predetermined amount or fluid instead of the steam in a steam discharging passage. A pressure loss coefficient is calculated based on the predetermined flow rate and the pressure difference by the controller. The controller consecutively calculates the amount of the steam based on the pressure difference and the calculated pressure loss coefficient, thereby outputting the same as a measurement value.
