HEAT MEDIUM BOILER SYSTEM

This heat medium boiler system (1) comprises: a combustion control unit (71) which controls the state of combustion for a heat medium boiler (2) on the basis of the deviation between a preset target temperature and the detected temperature of the heat medium measured by a heat medium oil temperature detection unit (36); a start-up detection unit (72) which detects the start-up of the heat medium boiler (2); and a start-up time target temperature setting unit (73) which, on the basis of the detection temperature T0 detected by the heat medium oil temperature detection unit (36) at the point oftime t0 at which the start-up of the heat medium boiler (2) is detected by the start-up detection unit (72) and a preset temperature increase rate p per unit time (rate/time), sets the target temperature SP(t) at time t (t >= t0) using the following Equation 1: SP(t) = p(t-t0) + T0 (Equation 1). 载热体锅炉系统(1)具备：燃烧控制部(71)，其基于预先设定的目标温度与由载热油温度检测部(36)计测的载热体检测温度的偏差来控制载热体锅炉(2)的燃烧状态；起动检测部(72)，其检测载热体锅炉(2)起动；以及起动时目标温度设定部(73)，其基于由起动检测
