Abstract

The invention relates to a thermodynamic system and method with the mixed application of the solar energy and a fuel oil gas boiler. The system comprises a solar heating device, a water-steam separator and the fuel oil gas boiler. The solar heating device comprises a water inlet and a water outlet which is connected with the water-steam separator. The fuel oil gas boiler comprises a boiler inner cavity, a combustor arranged in the inner cavity of the boiler, a steam conveying pipe arranged on the upper portion of the inner cavity of the boiler and a heat exchanging coil which is arranged in the inner cavity of the boiler. The inner cavity of the boiler comprises a water storage layer and a steam layer which is arranged above the water storage layer and communicated with the steam conveying pipe. The outlet of the heat exchanging coil is communicated with the water inlet of the solar heating device through a circulation pipe, and the circulation pipe is provided with a circulation pump. The lower portion of the water-steam separator is provided with a communicating pipe communicated with the heat exchanging coil. Due to the fact that the solar heating device and the fuel oil gas boiler are used in cooperation, the requirements for supplying steam and hot water are achieved, the fuel oil is reduced, and the thermodynamic system has the advantages of fully utilizing the solar energy, saving energy and reducing emissions.

Description

technical field [0001] The invention relates to a thermal system for heat supply, in particular to a thermal system and method for mixed application of solar energy and fuel gas boilers, which can utilize both thermal energy of solar energy and a burner as a heat source. Background technique [0002] Hydrothermal steam is the most commonly used industrial heat source and working medium, and its application is very extensive. Among them, water vapor can be used in various occasions such as cooking in the kitchen and industrial production steam; while hot water can be used in heating, industrial hot water, shower applications and other occasions. [0003] Traditional steam generation relies on coal-fired or oil-fired gas boilers. Due to the serious air pollution caused by the exhaust gas of coal-fired boilers, it has been generally banned. Due to the low pollution emission of oil-fired gas boilers, coal-fired boilers are gradually replaced. However, the use cost of oil-fired...
