Description

technical field [0001] The invention belongs to the field of thermal measurement, and in particular relates to an online measurement device and method for pulverized coal parameters of a power plant boiler in combination with dual laser sensors. Background technique [0002] Improving boiler efficiency and reducing pollutant emissions in thermal power plants is one of the key issues for the country to implement energy conservation, emission reduction and environmental protection. Among them, the real-time online measurement of the concentration, velocity and particle size of pulverized coal particles in the pulverized coal pipeline of the power plant boiler plays an important role in energy saving, emission reduction and optimal control. However, due to its complex flow as a gas-solid two-phase flow, it brings many difficulties to the measurement. [0003] At present, the commonly used on-line measurement methods for the concentration, velocity and particle size of pulveriz...
