Description

TECHNICAL FIELD

[0001] The utility model relates to the field of gas boiler especially relates to a kind of gas boiler noble metal magnetization catalytic energy-saving device. BACKGROUND

[0002] Beijing is one of the cities with the largest natural gas consumption in China. In the past decade, Beijing's natural gas consumption has been increasing year by year, and reached 19.91 billion cubic meters in 2022. The Beijing Municipal Administration Committee released the "14th Five-Year" Gas Development Plan for Beijing, which indicates that the annual consumption of natural gas should be controlled within 20 billion cubic meters by 2025. The main fuel for heating in Beijing Thermal Group is natural gas, and the current annual consumption of natural gas reaches 7 billion cubic meters, which is a major consumer of natural gas in Beijing. To achieve the goal of reducing gas consumption, it is very important to improve the efficiency of natural gas combustion. Currently, there are two types of catalytic devices that can improve the efficiency of natural gas combustion: one is a magnetic energy catalytic device, and the other is a catalyst catalytic device.

[0003] Magnetic energy catalytic technology started early, and scientists have been researching fuel magnetization since the mid-1960s. The basic working principle of this technology is fuel magnetization, which involves applying a strong magnetic field to the fuel to refine the particles, reduce the particle size, and increase the dispersion characteristics of the fuel, improve the combination with oxygen, achieve complete combustion, save fuel, and reduce pollution.

[0004] The catalyst catalytic device mainly uses various catalysts to catalyze natural gas. Compared with the problems of flame combustion, catalytic combustion has the advantages of low ignition temperature, stable combustion, low pollution, and low energy consumption, and is recognized as an ideal combustion method with high combustion efficiency and near-zero pollutant emission. In the future, the combustion of fuels such as natural gas, fossil oil, and coal may develop towards catalytic combustion. Generally speaking, the low-temperature activity and high-temperature stability of catalysts are contradictory, and the key to catalytic combustion technology lies in finding a catalyst with good activity and stability within a certain temperature range. Currently, taking methane combustion as an example, catalysts are mainly divided into two categories: one is a supported noble metal catalyst with good catalytic activity at low temperatures; the other is a non-noble metal oxide catalyst with stable catalytic performance at high temperatures, including simple transition metal oxides, perovskite oxides, and hexaaluminate.

[0005] However, there is no natural gas energy-saving device for gas boilers that simultaneously uses magnetic energy catalytic devices and catalyst catalytic devices in the prior art. Therefore, how to develop a gas boiler noble metal magnetization catalytic energy-saving device has become a problem to be solved by technical personnel in the field. UTILITY MODEL CONTENTS
