A biomass fuel boiler assisted solar hot water heating system and control method

Abstract

The invention discloses a biomass fuel boiler-assisted solar hot water heating system and a control method. The system includes a heat storage energy-saving kang, a heat source, room heating and domestic hot water equipment, a connected circulating water pipeline and a circulating water pump; The heat source is a solar water heater and a biomass fuel boiler, and the solar water heater is given priority by controlling the switch to supply hot water to the heat storage energy-saving kang, and when the solar energy is insufficient, the biomass fuel boiler is used to assist in providing hot water; the biomass The smoke outlet of the fuel boiler is connected through the smoke inlet of the energy saving and emission reduction flue wall. The present invention creatively designs a heat storage energy-saving heated kang, and ingeniously designs the energy-saving and emission-reducing flue wall to connect with the exhaust port of the biomass fuel boiler, and at the same time realizes the continuous supply of the hot water system in a low-cost manner. hot. It has the advantages of high heat exchange efficiency, low pollutant emission, high indoor air quality and heating quality.

Description

technical field [0001] The invention relates to the technical field of solar heating systems, in particular to a biomass fuel boiler-assisted solar hot water heating system and a control method. Background technique [0002] Today, coal is the main energy source for heating in winter in rural areas in northern my country. The amount of coal burned for heating per household is about 1-2 tons per year. The consumption is huge, and the smoke emitted after combustion causes environmental pollution. At the same time, the heating methods in the northern region are mainly stove heating and boiler combustion heating. The smoldering coal in the stove can easily cause the surface of the stove to be heated unevenly. At the same time, the harmful smoke generated during the smoldering process penetrates into the room through the gaps in the stove surface, and the indoor air quality deteriorates. In addition, it is troublesome to add fuel in the boiler and stove, which will pollute the i...

Problems solved by technology

[0005] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a biomass fuel boiler-assisted solar hot water heating system and a control method to solve the problem of large coal consumption in winter heating of farm houses in northern areas and the fact that existing solar water heaters only use For domestic hot water, it is troublesome to replace the fuel when the existing bio-fuel kang is used, the indoor air quality is low, and the environmental pollution caused by the combustion of coal and bio-fuels, etc.
