The brief introduction of biogas combustion chamber:

1. combustion chamber, moulding is cuboid or square, also can be designed to the solid of other shapes, as appearance such as spherical, round platform, terrace with edges, and the spatial modelling mutually combined by these solids.Its size needs to determine according to practice.This room, its large I builds up long 8 meters, and wide 4 meters, the combustion chamber of high 5 meters, also can build up other greater or lesser specifications.The bottom surface of each combustion chamber, arranges burner and combustion spray gun, by biogas and air by 1: 10 ratio evenly spray in combustion chamber, make it Thorough combustion, generation heat.The gas of base injcction, its intensity differs.The both sides of wall, Ye You secondary injection district.

Design pressure meter in combustion chamber, surveys the indoor pressure of meter at any time.

2. during methane normal combustion, the highest temperature can reach 1200 DEG C, and discharges a large amount of heat energy.Under 1 cubic metre of biogas status of criterion, the heat of 17911-25075 kilojoule can be discharged, be roughly equivalent to 0.7 kilogram of gasoline, or the heat that the raw coal of 1 kilogram provides.

3., in the bottom of combustion chamber, the air-flow of the varying strength ejected, the mist that intensity is high can make flame rising combustion, has flame at middle part and top.Burner has combustion front, and the gas of injection is more weak, at base burning.In addition, for increasing the effect of indoor even flame burning, before and after combustion chamber, the suitable position of two walls, rationally arranges spray-hole, suitably sprays varying strength mist, makes up the defect of indoor non-uniform combustion and combustion quantity not sufficient.

4. natural pond oxygen gas mixture sprays into and wants evenly, combustion gas physical efficiency be made to spread apart.Cause gas when burning, strong and weak according to air-flow, limit is spread, and burns in limit, and homogenous combustion.Such vaporization water pipe that can make is heated evenly.This just requires there is higher requirement technically, reaches suitable, in right amount; Power, size is different.Sufficient combustion, calorific value reaches requirement, and indoor invariablenes pressure of liquid is within the scope of certain numerical value.

5. combustion chamber, also will arrange peep hole in many places, to open observation ward's combustion situation at any time.

6. the hot-water line of discharge in combustion chamber, claims vaporization water pipe.Be advisable with ellipse.The laterally interlaced arrangement of vaporization water pipe multilayer.Rising flame can not be blocked, interior flame homogenous combustion can be impelled again, increase heating surface area.Arrangement generating tube, perpendicular vertical vertical with wide of this cylindroid cross section, towards locular wall, parallel with it.So not only should not block rising flame, can also heating surface area be increased simultaneously, better absorb heat, accelerate the vaporization of the aqueous solution, and when making flame increase, curve rises, and increases the utilization rate of heat.

7., as a combustion chamber does not reach the effect needed for vaporization, can be connected multiple combustion chamber, increase vapourizing temperature step by step.The circulating water pipeline be connected with each room, outer surface is provided with attemperator, prevents the heat losses of vaporize water.

8. top, combustion chamber is hemisphere, treats waste air in order to assemble.Under hemispherical cover, it is smoke evacuation wall with holes.The flame of combustion chamber combustion is blocked in its effect on the one hand, makes it Thorough combustion.The waste gas in combustion chamber can be got rid of rapidly on the other hand, reduce its pressure.

9. appropriate design smokejack is wanted in combustion chamber, guarantees that waste gas is unimpeded, reduces room pressure, and Accident prevention occurs.Interior space part is combustion zone, is also the vaporize water area under control of placement of multiple layers arrangement.Shi Ding center arranges main smokejack, and remainder arranges multiple secondary smokejack at rational position.Main smokejack is established two or more shunting by-paths, also will assist on this by-path and major-minor two exhaust pumps are set.When main smokejack is got rid of not smooth naturally, major-minor exhaust pump can be driven according to situation and accelerate exhaust, to reduce indoor pressure.In like manner, as required, each secondary smokejack also can arrange major-minor exhaust pump, auxiliary acceleration is vented.Indoor are made to have the safe pressure values of a constant range, to keep the safety in production.

10. combustion chamber internal layer is one deck flame retardant coating, and centre is high pressure resistant steel construction, and skin is overcoat.Between flame retardant coating and steel construction, there is one deck insulating.Prevent steel construction from reducing its voltage endurance capability because being heated.Some big-and-middle-sized combustion chambers, on steel construction, design crisscross girder steel, mutually be connected between each girder steel, with enhanced burning room compression strength and stability.

11. hot gases of discharging from major-minor smokejack, through cooling tower by its heat absorption.Hot water waits until and produces natural pond liquid use, or vaporize water is used as in backflow.
