Abstract

The invention discloses a silicon oxide heat storage ball which comprises the following components in percentage by weight: 25-35% of silicon dioxide, 20-30% of silicon carbide, 30-40% of aluminum oxide, 0.3-1% of ferric oxide, 1-3% of calcium oxide, 1.5-3% of magnesium oxide, 0.1-1% of potassium oxide, 0.1-1% of sodium oxide and 0.3-1.2% of titanium dioxide, totaling 100%. The silicon oxide heat storage ball disclosed by the invention has excellent performances of high density, high thermal shock resisting stability and high heat conductivity at the same time, has high strength, high hardness and good resistance to chemical corrosion and meanwhile has a good anti-oxidizing effect, so that the silicon oxide heat storage ball is particularly suitable for situations that the environment is harsh and a heat storage chamber is subjected to severe oxidation corrosion. The service life of the silicon oxide heat storage ball is 5-6 times longer than that of a heat storage body in the prior art.

Description

technical field [0001] The invention belongs to the technical field of heat storage combustion, and relates to a silicon oxide heat storage ball. Background technique [0002] Regenerative combustion technology is the most advanced high-temperature air combustion technology in the world today, and is recognized as a revolution in combustion technology by the international combustion industry. This technology uses the control of the reversing valve to repeatedly perform alternate operation, uses the regenerator equipped with heat storage materials to preheat the combustion air to above 1000°C, and reduces the temperature of the exhaust gas to below 200°C, thereby realizing Ultimate recovery of flue gas waste heat. Compared with the traditional combustion process, the biggest feature of regenerative combustion technology is fuel saving and reduction of combustion noise, so it is also known as one of the key technologies in the 21st century. In 1998, more than 50 companies in...
