Boiler positive balance test: A method for calculating the thermal efficiency of a boiler by measuring its various heat losses. (Wrong) This is an anti-equilibrium test
Wrong. Definition of boiler steady-state balance test: A test that determines the thermal efficiency of a boiler by measuring the heat input and the heat effectively utilized by the boiler.
Positive balance: It involves directly measuring through experiments the heat effectively utilized by the boiler (i.e., the heat required to generate steam), the coal consumption per hour, and the lower heating value of the coal, in order to calculate the boiler’s thermal efficiency. Counterbalance: It involves directly measuring and calculating various heat losses of the boiler, and then determining its thermal efficiency.
