Problems solved by technology

[0002] At present, the known oil and gas combustion technologies all adopt the traditional complete air combustion. "Because most of the 78.9% inert gas in the air is nitrogen, not only does not help combustion, but also 'takes' a large amount of nitrogen from the furnace." Oxygen (every 1 ton equivalent of N in the combustion product reacts to generate NO 2 , it needs to consume more than 2.29 tons of oxygen, resulting in an increase of about 11,000 m in the non-oxygen excess air supply of the inert gas blown into the boiler furnace by the blower 3 , based on the exhaust gas temperature of 200°C at 15°C, the additional incremental heat exhaust gas is 18,500 nm 3 , the sensible heat loss is as high as 1.13 million kcal) and generate nitrogen oxides that are extremely harmful to human health (according to a research report by an authoritative organization in Western Europe in the 1990s that sounded the alarm to all mankind, if according to the end of the 20th century If the nitrogen oxide pollution situation in Western Europe is left unchecked, then the males in this environment will gradually lose their reproductive ability), and at the same time, the flue gas emission of nitric acid gas will also be greatly increased.”

Therefore, the national “coal-to-gas” work over the past few years has been seriously lagging behind in scientific research in this area. It is clear that the culprit of pollution that really causes smog in the process of natural gas combustion is nitric acid gas. The "persistent disease" of environmental pollution that cannot be avoided by people in the whole society and must be eradicated... The current oil and gas burners (even if oxygen production technology is used to supply wind It still consumes the oxygen of the earth's air without exception, it can only aggravate the crisis of "a sharp drop in oxygen concentration" in the earth's atmosphere), and has been unable to adapt to ZL201210566497.4 "A Mg Catalyzed Water-based Combustion-supporting Coal, Gas Boilers, kilns and furnaces with oil, low carbon, sulfur and nitric emissions" The national and even global development of new combustion science is bound to be based on the revolutionary demands and rapid quantification of energy (according to statistics, China alone has 620,000 coal-fired boilers and about 460,000 industrial boilers , with a total capacity of 2 million steam tons / hour, and it is estimated that industrial boilers with a capacity of less than 20 steam tons / hour are the targets of coal-to-gas conversion, accounting for 85% of the total, reaching as many as 530,000 units; in addition, there are normal and low pressure seasons for heating in the north The boilers in operation are estimated to have a total capacity of 600,000 steam tons per hour, and there are 1.5 million large and small wall-hung boilers, etc., which are the vast market for coal-to-gas conversion in the future), which must be revolutionized and popularized with this energy revolution to meet The need for a national ultra-energy-saving and environmental protection major replacement
