Background technology
Biomass gasification technology is just at development, and its production and democratic meeting to human society produces huge potential impact.
Biomass gasification burning is a kind of low-calorie gas, is about 1100 kilocalories/M
3left and right, for the heat energy utilization obtained and the effect of environmental protection, the abundant burning of combustion gas and convenient application seem very important.
The general kitchen range that adopt infrared ceramic porcelain plate to make of traditional biomass gasification burning burning, there is the problems such as oxygen supply distribution is not convenient, ignition temperature is lower, the easy obstruction of the aperture of ceramic wafer in this kitchen range.Must invent simple, practical device and carry out biomass burning gasification combustion gas, effectively solve the problem that conventional red outside line ceramic wafer kitchen range exists.
The quality of fuel gas buring kitchen range combustion efficiency depends on the oxidation effectiveness of combustion gas, and it comprises the three large factors such as mixability (being called rapid degree), the time that combustion gas stops in combustor cavity of control, air and the combustion gas of air total amount.
1. total oxygen-supplying amount >=oxygen demand (be generally suitably to exceed oxygen demand in practical application, peroxide amount is 1 ~ 15%).This requirement is joined oxygen blower fan and is being joined in oxygen total amount to regulate and control, and the maximum oxygen-supplying amount of blower fan should exceed the more than 150% of normal oxygen demand.
2. rapid degree.Rapids degree refers to the mixability of air and combustion gas, increases rapid degree and can adopt to join in advance oxygen and form the measure such as eddy current and realize.
3. burning time.Combustion gas will stop enough burning times in combustor cavity, and the method for prolonging burning time has two: one, increases the length of combustion chamber; The 2nd, the volume of increase combustion chamber.
Summary of the invention

The technique effect of this device is:
1. combustion gas enters mixture pipe after mixing with air, then enters hybrid chamber (we are referred to as to join in advance oxygen), is conducive to combustion gas and fully mixes with air, improves the rapid degree of burning gases.
2. incoming air conduit is arranged on Gas Pipe side, and both have a certain degree at shape
α, accelerate mist to moving ahead, be conducive to prevent that " tempering " situation from occurring.
3. Inlet Manifold Design becomes in the same way, and can form the effect of " eddy current " when combustion gas is burnt in combustion chamber, burns more abundant, improves the rapid degree of burning gases in combustion chamber, and extends the time that combustion gas stops in combustion chamber.
4. banking fire plate contributes to control the excessive speed of flame, extends the time of staying of combustion gas in combustion chamber; Aperture above banking fire plate can ensure that fraction flame passes.
5. secondary intake pipes is realized secondary air distribution, and aperture and kitchen range wall form inclination angle in the same way, increases fuel gas buring and produces stronger " eddy current " effect, and prevent that an air distribution is because situation generation too drastic and that put out flame.
