ABSTRACT
This paper introduces the Shuyue Smoke-free Combustion Efficient Technology (SYSFECT), a revolutionary technology that can be used in coal, oil and gas fired boilers to achieve the major benefits of near-zero emission of flue gases as well as greenhouse gases to the air, of highly improved combustion efficiency and thermal efficiency, savings on energy sources, and elimination of huge expenditure that would otherwise be used on installation, operation and maintenance of pollution control facilities.
The analyses of the newly invented combustion theory, the key component of the technology Core Panels, and the boiler design mechanism will be made. The SYSFECT utilizes the magnetic field vortex flow theory to help create an intensified high temperature combustion environment. Composed of various ingredients and acting as catalytic agents, the core panels are placed inside the boilers to create the magnetic field under the high degrees of combustion temperature, to participate in the chemical reactions to decompose CO2, SO2, NOx and to help form incombustibles from the chemical reactions. The SYSFECT’s gasification design presents unique characteristics: 1) consisting of inbound and outbound pipes to cycle the incompletely combusted smoke and gases, and 2) an underground chamber to cool off the smoke and form sediments before the gases pass the baffles to be released into the air. Using the SYSFECT, the whole boiler design system not only is a combustion body, but also functions as a dust and particulates precipitating mechanism. The technology provides a low-cost and distinctive way to control and constrain the flue gas from emitting into the air.
With catalytic agents and under the highly intensive combustion environment, the SYSFECT boilers are able to take, as energy sources, coal of low quality (with sulphur content > 1.1%), oil, natural gases, even "secondary" fuel resources such as gangue, slag, distiller’s chaff and crop stalks, as well as such improbable materials as yellow clay, forest humus soil, volcano ashes and oil shale.
The testing results and the measurement of the various combustion parameters for the SYSFECT boilers will also be presented and found to greatly exceed the

一、 前言:
当前随着经济的快速增长,能源紧张,环境污染严重已成为世人瞩目共识的事实。就此问题无论是在当前还是在今后都是应急待解决的大事。
能源是人类的经济命脉。地球中的现有能源如何综合利用,如何能合理有效利用,这是很重要的问题。在多种能源中贮量与现时应用量最多的、燃用上最廉价的应是煤炭资源。
可是燃用煤炭为能源产生的浪费大、污染严重,这是由于自有燃烧设备以来,燃烧方式的不合理所致。
目前,在工业窑炉上使用的燃煤技术大约有下面几种:
1) 层燃方式,如反射炉、倒焰窑等。这是最常用的燃煤工业窑炉,其缺点是不能长时间连续稳定燃烧,只能间歇运行,其热效率和生产效率低下,在生火或加煤时易产生浓烟,环境环恶劣。
2) 煤粉燃烧方式,其燃烧稳定连续,燃烧气氛和燃烧强度易于调节。但是,其火焰中含有大量的飞灰,只能用于少数特殊的窑炉,如水泥转窑等,不适用于多数要求清洁火焰的工业窑炉。
3) 煤气化技术。这是目前燃煤工业窑炉现代化改造常用的方法。但由于煤气发生炉投资大,运行成本高,煤气转化效率低(只有50-70%),其经济性难以为一般工业企业所接受。
4) 水煤浆燃烧技术。水煤浆燃烧方式接近于燃油。但水煤浆也存在灰份较高(5~10%),火焰洁净度不够的缺点。同时,水煤浆的价格比煤粉高得多。
5) 煤粉液排渣旋风燃烧技术。这种燃烧方式和煤粉燃烧相似,但可在燃烧过程中实现灰渣捕集,可降低火焰含尘浓度,是一种有发展潜力的工业窑炉用洁净燃煤方式。典型的煤粉液排渣旋风燃烧器为美国TRW公司的燃烧器。我国也有不少科研单位和企业试图将煤粉液排渣旋风燃烧器用于燃煤磁流体发电或工业窑炉中,做了大量的试验研究工作,取得了许多经验教训。目前,煤粉液排渣旋风燃烧器由于捕渣率不够高,风口易结渣,结构复杂而难以用于一般工业窑炉。
以上所述,目前仍没有一种令人满意的工业窑炉燃煤技术。怎样才能使燃煤设备合理的燃烧,能够充分发挥出煤炭的应有效能。从而达到省煤、高效,从根本上控制污染源的抑制,达到节燃、降耗、降低温室效应、减轻空气污染。
对此,本人在多年的研究、实践中,研究出适合燃煤、炉类,从而用炉到各种用途的锅炉、窑炉,大型炉、窑、电站发电锅炉,改变燃烧方式,促进燃烧效率的技术核心件——炉芯板。
二、炉芯板简介
这种芯板是用特殊材料和工艺自做而成,安装在炉膛内两侧,就可使燃煤在燃烧时发生根本的变化而不生烟不冒烟。并使锅炉简单化,不用锅炉以外的传统式脱硫除尘设备,不用大烟囱。
