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 China’s National Regulation for Boiler Air Pollution Emission Standards.  When installed and operated properly, SYSFECT boilers are able to achieve 98% combustion efficiency, 60-70% of thermal efficiency, 15% saving in power and 25% in coal.  While it is apparent that the SYSFECT will serve environmental protection initiatives, it is expected that the technology will attract many major commercial usages in energy industry, utility industry as well as in agricultural, industrial (waste management, pulp and paper etc.) and residential applications

一、 前言

當前隨著經濟的快速增長,能源緊張,環境汙染嚴重已成為世人矚目共識的事實。就此問題無論是在當前還是在今後都是應急待解決的大事。

 

能源是人類的經濟命脈。地球中的現有能源如何綜合利用,如何能合理有效利用,這是很重要的問題。在多種能源中貯量與現時應用量最多的、燃用上最廉價的應是煤炭資源。

 

可是燃用煤炭為能源產生的浪費大、汙染嚴重,這是由於自有燃燒設備以來,燃燒方式的不合理所致。

 

目前,在工業窯爐上使用的燃煤技術大約有下麵幾種:


1)
層燃方式,如反射爐、倒焰窯等。這是最常用的燃煤工業窯爐,其缺點是不能長時間連續穩定燃燒,隻能間歇運行,其熱效率和生產效率低下,在生火或加煤時易產生濃煙,環境環惡劣。


2)
煤粉燃燒方式,其燃燒穩定連續,燃燒氣氛和燃燒強度易於調節。但是,其火焰中含有大量的飛灰,隻能用於少數特殊的窯爐,如水泥轉窯等,不適用於多數要求清潔火焰的工業窯爐。


3)
煤氣化技術。這是目前燃煤工業窯爐現代化改造常用的方法。但由於煤氣發生爐投資大,運行成本高,煤氣轉化效率低(隻有50-70%),其經濟性難以為一般工業企業所接受。


4)
水煤漿燃燒技術。水煤漿燃燒方式接近於燃油。但水煤漿也存在灰份較高(5~10%),火焰潔淨度不夠的缺點。同時,水煤漿的價格比煤粉高得多。


5)
煤粉液排渣旋風燃燒技術。這種燃燒方式和煤粉燃燒相似,但可在燃燒過程中實現灰渣捕集,可降低火焰含塵濃度,是一種有發展潛力的工業窯爐用潔淨燃煤方式。典型的煤粉液排渣旋風燃燒器為美國TRW公司的燃燒器。我國也有不少科研單位和企業試圖將煤粉液排渣旋風燃燒器用於燃煤磁流體發電或工業窯爐中,做了大量的試驗研究工作,取得了許多經驗教訓。目前,煤粉液排渣旋風燃燒器由於捕渣率不夠高,風口易結渣,結構複雜而難以用於一般工業窯爐。

 

以上所述,目前仍沒有一種令人滿意的工業窯爐燃煤技術。怎樣才能使燃煤設備合理的燃燒,能夠充分發揮出煤炭的應有效能。從而達到省煤、高效,從根本上控製汙染源的抑製,達到節燃、降耗、降低溫室效應、減輕空氣汙染。

對此,本人在多年的研究、實踐中,研究出適合燃煤、爐類,從而用爐到各種用途的鍋爐、窯爐,大型爐、窯、電站發電鍋爐,改變燃燒方式,促進燃燒效率的技術核心件——爐芯板。

 

二、爐芯板簡介

 

這種芯板是用特殊材料和工藝自做而成,安裝在爐膛內兩側,就可使燃煤在燃燒時發生根本的變化而不生煙不冒煙。並使鍋爐簡單化,不用鍋爐以外的傳統式脫硫除塵設備,不用大煙囪。
