Zusammenfassung:	The utility model relates to a boiler with a metering thermostatic coal-feed unit. The boiler comprises a combustion chamber, a flue, a door and a hot fume outlet. The boiler is connected with a metering thermostatic coal-feed unit which comprises a temperature detector, a control system and a metering coal feeder. The temperature detector is disposed at the hot fume outlet. The metering coal feeder feeds coal to the combustion chamber through a conveyer belt. The control system comprises a first controller, a second controller and a temperature threshold storage. The first controller calculates theoretical coal feed according to a difference between measured value and temperature threshold. The second controller monitors actual coal feed through a speed sensor and a weight sensor on the metering coal feeder, compares called theoretical coal feed, and ends coal feeding when the actual coal feed reaches the theoretical coal feed. By metering coal feed according to the temperature of hot fume, energy can be sav
