1. a temperature-regulating water tank; 2. and (5) adjusting the power by multiple stages of fire.

The temperature-regulating water tank can buffer the fluctuation of the outlet water temperature caused by the inlet water temperature and the flow, and can control the outlet water temperature by regulating the flow or mixing cold water, but because the power of the heater is constant, the parameters of the inlet water temperature, the flow, the outlet water temperature and the like are mutually involved, and the temperature-regulating water tank is difficult to be matched with a system to achieve better technical indexes; the inertia of the water temperature of the system is increased by the temperature regulating water tank, the water temperature is reset, the equipment is started, the water in the temperature regulating water tank needs to be waited to be gradually replaced by the water with the needed temperature, the waiting and water waste is caused, and the clean water is more valuable in the field environment; the temperature regulating water tank makes the mechanical structure and the electrical control of the equipment become complicated, increases failure points and reduces the overall reliability of the equipment; the coil pipe type fuel oil heater is suitable for the working condition of high-pressure water (the water pressure is higher than 10MPa), but the high-pressure temperature-regulating water tank belongs to a pressure container, the technical threshold is high, the overall cost of the equipment is increased, and meanwhile, the safety is reduced.

The multi-section fire power regulation technology is different from continuous power regulation, a plurality of oil nozzles (no less than two) are arranged in a heater, under the condition that oil supply pressure is the same, the injection flow of each oil nozzle is different, the opening and closing of each oil nozzle are controlled through an electromagnetic valve, and the oil nozzles are independently or in combination injected, so that the heat exchange power of the heater is changed.

SUMMERY OF THE UTILITY MODEL
