Continues fast development and population quantity along with the world economics grows rapidly, the humanity increases inevitably unceasingly to the energy demand, however the present humanity's livelihood fossil energy rapidly is reducing actually. According to the forecast, on the earth will contain may develop the use the coal and the petroleum fossil energy separately in 200 and 40 years exhausts, but the natural gas only will also be able to use about for 60 years. At the same time, because the fossil energy overdevelopment use brings the environmental pollution and the global warming question day by day also prominent.Because the biological mass energy has distributes, renewable, the cost broadly merits and so on low, low pollution becomes one of fossil energy best substitutes.Various countries through each kind of transformed technology biological mass energy effectively development and use.This topic is raised precisely "the integrated type lives the material multiple dodges the fast thermal decomposition liquefication production biology fuel oil new technology" in the foundation national 863 topics to propose, systematically has comprehensively collected the domestic exogenous material gasification technology research material, and has carried on the study and the research thoroughly. In this foundation, chooses a set to live the material to vent one's anger the air feeder, and studies and the design with this kind of straw coal gas for the fuel high efficiency straw gas firing machine, replaces the original diesel oil achievement to live the material thermal decomposition liquefication system to take in the biological fuel oil technology to live material and the heat-carrying agent heat installation energy dryly, as our country; the biological fuel oil formalization production provides the new power take the time, to reduces the biological fuel oil formalization production energy consumption and the production cost, has the important research practice value and the economical significance. The main contents of this article are as follows: carries on lives the material to vent one's anger the air feeder shaping the energy computation, chooses set of suitable fresh materials to vent one's anger the air feeder; studied and has grasped the gaseous combustion and the jet flow theory, studied and has analyzed the flame-propagation and the flame stable influence factor; pair carries on lives the material fuel gas the combustion characteristic to conduct the fundamental research; narrated the atmospheric type to live the material fuel gas burner with emphasis the principle of work and the design method, including: eductor fundamental equation inferential reasoning computation; spray nozzle diameter computation and installment; eductor throat diameter computation; Burner forehead fire hole diameter computation and so on. Easy to appear in view of the combustion process in escapes the fire phenomenon to adopt has prevented the measure, and selected the electronic pulse auto-ignition method to carry on the ignition.This article develops the high efficiency lives the material fuel gas burner versatility to be good; catches fire rate is high; the burning stability is good, does not escape the fire, not tempering, not yellow flame; the combustion efficiency is high. Its technical specification also very is high, lives the material fuel gas adaptation scope is 4.6~6.6MJ/m~3; the rated power is 900kW; combustion efficiency 90%; catches fire rate is 100%. Should live the material fuel gas burner the development for to live the material fuel gas to provide the premise by the countryside simple kitchen work to the large-scale industrialization application.
