2. The utility model discloses can be in the boiler normal operating stage (when need not throw oil promptly), will the oil pump shutdown to save a large amount of electric energy. The reason is as follows: the utility model discloses balance jar in save and satisfied the oil pump start-up period boiler throw the combustion-supporting required oil mass of oil. The working process can be described as follows: when the boiler normally operates, the oil pump does not need to be put into operation; when the boiler has an emergency (such as some equipment faults) and needs to be oiled for combustion supporting, firstly, the boiler is stably combusted by using the fuel oil stored in the balance tank, the oil pump is started, and after the oil pump runs normally, the electric valve at the inlet of the balance tank is opened to supplement the fuel oil into the balance tank, so that the fuel oil system is recovered to a normal running state.
