Description
Technical field
It is more particularly to a kind of to be fired using fuel oil for fuel the present invention relates to a kind of manufacture method of ignition of the boiler device
The manufacture method of the igniter of burning.
Background technology
At present frequently with oil gun burner on the Thermal generation unit in thermal power plant, and there is combustion for oil gun burner
The problem of oil stream amount adjustable range is small.In order to increase the adjustable range of burner fuel flow, many new combustions are developed
Burner technology.
The Chinese patent application of Application No. 200610042595.2 discloses a kind of burner for including gasification of fuel oil body,
The powder metallurgical body of micropore is provided with the fuel flow path of gasification body (the fuel-gasifying cooking device corresponded in the present invention),
This can make fuel oil be refined as mist of oil after by powder metallurgical body；When the pressure very little of fuel oil is conveyed, due to micro-
The capillarity of the powder metallurgical body in hole, fuel oil can also pass through powder metallurgical body and form mist of oil, due to being with infiltration
With capillary action transport fuel oil, therefore fuel flow has larger adjustable range, but the gasification body is provided in interior preheating ring
Between outer preheating ring, preheated by the two preheating rings, this preheating method has both sides deficiency：When preheating
For efficiency than relatively low, the substantial amounts of heat of preheating ring is not used for heating and gasifying body, but from preheating ring and gasification body non-planar contact surfaces
It is lost in, this make it that the temperature required time that gasification body reaches 300-400 DEG C is longer, disclosed in document when black furnace starts,
Need the temperature that can just make gasification body reach 300-400 DEG C required for 15 minutes；Second, machining accuracy and installation essence to preheating ring
Degree requirement is very high, adds assembly cost.
The content of the invention
For the problem of pre- thermal efficiency is low, assembly cost is high existing for existing fuel-gasifying cooking device, the present invention provides
A kind of manufacture method of fuel-gasifying cooking device.
Main idea is that preheating body is arranged in the powder metallurgical body in fuel-gasifying cooking device so that pre-
Hot body lifts the efficiency of heating surface of fuel-gasifying cooking device, while reduces assembly cost.
Technical scheme is as follows：
The inner cylinder set in fuel-gasifying cooking device, including outer barrel and outer barrel, the internal diameter of outer barrel is more than the outside diameter of inner cylinder, interior
Cylinder is parallel with the axis of outer barrel or overlaps, and is the powder metallurgical body of sintering, the powder of the sintering between the inner cylinder and outer barrel
There is hole between the metallurgical powder particle of metallurgical body, preheating body, the preheating are provided with the powder metallurgical body of the sintering
Body preheats body for Electric heating and is connected with fuel-gasifying cooking device external power supply.
The fuel-gasifying cooking device along axis one end for oil, gas upstream end, the other end for oil, gas outlet side, inner cylinder
Wall closes on oily, gas outlet side the preformed hole being provided with for dredging flow, and the preformed hole penetrates inner cylinder barrel.
Groove is provided with the inner surface of the outer barrel and the outer surface of inner cylinder.
The inner cylinder, outer barrel and powder metallurgical body are homogeneous material.
The material of the inner cylinder, outer barrel and powder metallurgical body is stainless steel.
A kind of manufacture method of the fuel-gasifying cooking device, includes the following steps：
Prepare inner cylinder and outer barrel, inner cylinder outside diameter is less than outer barrel internal diameter, and outer barrel is longer than equal to inner cylinder；
A0, clean the inner surface of outer barrel and the outer surface of inner cylinder；
A1, process preformed hole on outer barrel and inner cylinder；
A2, process groove on the inner surface of outer barrel and the outer surface of inner cylinder；
A, inner cylinder is inserted into outer barrel, make inner cylinder parallel with the axis of inner cylinder or overlap；
B, the relevant position being arranged at preheating body between outer barrel and inner cylinder；
C, the position of preset clearance is being needed to fill the obturator with corresponding preset clearance shape；
D, metallurgical powder is filled into the gap between outer barrel and inner cylinder, makes that there is hole between metallurgical powder particle；
E, the metallurgical powder between outer barrel and inner cylinder is sintered.
Technique effect：
The present invention can will preheat the exhausted of body since preheating body is arranged in the powder metallurgical body in fuel-gasifying cooking device
Most of heat all passes to powder metallurgical body, and few partial heat wastes, therefore the efficiency of heating surface for preheating body is high, of the invention
Fuel-gasifying cooking device can make fuel-gasifying cooking device reach 300-400 DEG C within a very short time in the case of black furnace startup.
Further, since to setting position of the preheating body in powder metallurgical body without very strict requirements, therefore assemble
It is of low cost.
The preformed hole that sets for dredging flow is closed on oily, gas outlet side in inner tube wall so that is passed through from inner cylinder
Air-flow can be flow to from the preformed hole before powder metallurgical body is located at the oil of fuel-gasifying cooking device, gas outlet side, that is, is flow to
Powder metallurgical body front end, oil are discharged from there.This aspect allow from powder metallurgical body discharge oil immediately with air into
Row mixing, beneficial to oily fully burning；On the other hand, the air-flow for flowing to this one end of powder metallurgical body forms negative pressure at this, profit
Powder metallurgical body is penetrated in the oil positioned at the powder metallurgical body other end.
The groove processed on the inner surface of outer barrel and the outer surface of inner cylinder increases inner cylinder, outer barrel and powder metallurgical body
Contact area, make the combination of three more firm.
The material of inner cylinder, outer barrel and powder metallurgical body is all stainless steel so that three is more easy to be combined together, the combustion of formation
Oil gasification burner is firmer.
