WhatsApp: +86 18838072829A heat balance is an efficient tool to measure the actual state of a kiln system. It allows a better assessment of the heat consumption and reveals the potentials for improvements (regarding the thermal aspects). The principle of a heat balance is rather simple: we select our system limits for the balance and measure all inputs and outputs.
