Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with specific examples.

[0024] Put hydrogen, atomic absorbent, inert gas, oxygen regulator, and modified flame retardant into the burner, spray them out from different channels of the burner, and mix and burn outside the burner nozzle to obtain stable and adjustable length flame; wherein, the modified flame retardant is obtained by uniformly mixing the flame retardant and the surfactant. The formula of hydrogen, atomic absorbent, inert gas and oxygen regulator is shown in Table 1, and the formula of flame retardant and surfactant in the modified flame retardant, the length and temperature of the flame are shown in Table 2.

Abstract

The invention discloses a method for replacing carbon neutralization with building material industrial fuel. The method comprises the following steps that hydrogen, an atomic absorbent, inert gas, an oxygen regulator and a modified slow-burning agent are introduced into a burner, correspondingly sprayed out from different channels of the burner, and mixed and burnt outside a nozzle of the burner to obtain stable flame with adjustable length. Compared with the prior art, the method is simple to operate, low in cost and wide in combustion temperature range.

Description

technical field [0001] The invention relates to the field of carbon neutralization in the building material industry, in particular to a method for replacing fuel in the cement or gypsum industry, that is, replacing coal or natural gas with hydrogen. Background technique [0002] In the building materials industry, the largest carbon dioxide emission is the cement industry. The cement industry is the third largest energy-consuming industry in the world, accounting for 7% of industrial energy consumption, and the second largest carbon dioxide emission industry in the world, accounting for 7% of global carbon dioxide emissions. my country's cement industry will emit about 1.32 billion tons of carbon emissions (including power consumption) in 2020, accounting for about 80% of the building materials industry and about 13.5% of the country's total. The cement industry has a great impact on the realization of the "double carbon" goal of my country's building materials industry. T...
