A Method for Counterbalance Verification of Positive Balance Coal Consumption
The calculation methods for coal consumption in thermal power plants can be divided into two types:positive balance and negative balance.Positive balance is macro level,while negative balance is micro level.The positive balance method is to calculate how much standard coal is used and how much electricity is supplied per unit.The output electricity is easy to collect,while the input calorific value(coal quantity)×It is not easy to accurately calculate the low heating value.On the one hand,the low calorific value of coal needs to be sampled for testing and cannot be obtained in real-time.The results of coal sampling from a certain batch can only be used as a representative.There are corresponding standards for measuring the calorific value of coal,but there is uncertainty in sampling.The calorific value of coal is the most basic data,and if it is not accurate,it will make the calculated coal consumption meaningless;This is related to the measurement location and method,so it is particularly important to use counterbalance for verification.
