Abstract

The invention discloses a trough type heat collecting field boosting and mixing fuel injection adjustment system and an adjustment method, which belong to the field of trough type solar energy concentrating and heat collecting. The system includes a main oil tank, a main oil pump, a regulating oil tank, a regulating oil pump, a flow regulating valve, a fuel injector, and corresponding pipelines and auxiliary equipment. According to the oil temperature at the branch outlet of the collector field, the system uses the low-temperature heat transfer oil from the regulating oil tank to adjust the flow rate entering the injector through the flow control valve, and mixes with the heat transfer oil from the upstream collector to realize the adjustment of the collector field. The purpose of the outlet heat transfer oil temperature. On the basis of the existing branch flow and collector defocusing adjustment methods, the invention adds fuel injection adjustment means, so that the temperature adjustment of the heat conduction oil at the outlet of the collector field is more flexible and effective, and the deterioration of oil quality caused by local overheating is avoided. , greatly reduce the energy loss caused by the defocusing adjustment of the collector, improve the thermal efficiency of the trough collector field, increase the utilization rate of solar energy, and reduce carbon emissions.

Description

technical field [0001] The invention belongs to the field of trough-type concentrating heat collecting fields, and particularly relates to a trough-type heat collecting field boosting and mixing fuel injection adjustment system and an adjustment method. Background technique [0002] The trough solar collector field uses a parabolic trough concentrator to focus the sunlight on its own focal line, and installs a vacuum heat absorption tube on the focal line to absorb solar energy and heat the heat transfer medium; follow-up The power cycle of steam can be used to generate electricity or be used in other heat-using fields. The working medium of the collector field in the trough solar thermal power generation system is heat transfer oil, and the adjustment of the temperature of the heat transfer oil in the collector field is a key adjustment task in the operation of the collector field. [0003] At present, the adjustment method of the heat transfer oil temperature at the outle...
