Burner and manage technique:
Substantial pace fuel burner and ratio manage technique
Continuous cylinder warmth treatment method furnace demands the equal warmth provide, equally loading the cylinder, and needs to give large heating load alterations, so we choose ratio burning handle method.The sleeve tube on the burner nozzle will kind a high speed jet steam when burning, can stir up the within ambiance and similarly offer the warmth.The heating of each and every burner nozzle is ratio management.
In the ratio management program, the burner nozzle will instantly change the heating according to the temperature in the furnace, the electrical power, mixture ratio, spraying velocity will be altered to a best situation, which will effectively improve the burning potential and minimize the air pollution.Through the cooperation of the many burner nozzles, the heat movement will be uniformly dispersed in the furnace, which will boost the heating quality of the cylinder and temperature uniform.We also choose controller of substantial resolution and suitable power burner nozzle to get to a high linearity of the method.That kind of handle program is commonly utilised in metallurgy and device heat treatment sector.
Operating station handle program
That technique has the feature of expansibility, adopts the manage program:1 gauge- one burner nozzle or a single gauge- multi-burner nozzles.The instrument adopts Japan conductive company SRS3 type clever temperature management instrument.Through connect the signal of true temperature in the furnace and then estimate by pc to manage the on/off and dimension of the every single burner nozzle, in the meantime , every burner nozzle doing work condition can routinely go on according to the pre-established curve.And it will demonstrate the temperature manage point and its temperature and the curve(also has paperless recorder), present the functioning problem of the burner nozzle, and failure warning.
The distinct basic principle:The thermocouple will detect the temperature sign of extremely part furnace, then feed back again to temperature instrument to examine the tolerance in between the pre-established temperature and actual temperature, then handle the burner nozzle output via ratio control.
Alarm program and safety interlock system
Given that the fuel is nature gas, which is hazardous, so the safety method is necessary.All the nozzles are equipped with automobile ignition device and flame detection gadget, will output the warning signal when flame is out, the vehicle ignition device and flame detection unit will lower sown the solenoid valve, in the meantime there is indicator light-weight will inform which nozzle is down and start and stop the interlock gadget.Audible and visual alarm will alarm to remind the operator to offer with the failure in time.There will is true-time keep track of and failure report in our electric method.
CZPT equipment:Japanese conductive meter, Chit or Delixi reduced pressure electrical equipment, the cable wire is from inland famous brand name.Burner:Ignition controller, push swap, solenoid valve are from UAS Honeywell11 or German Krom, the hand valve and dish valve are from inland popular brand.
Principal content specifics:
1.The shell is welded by section steel and steel plate(substantial good quality steel)
3.High temperature refractory clay:HangCZPT
four.Higher temperature refractory brick:HangCZPT
5.CZPT Appliances:CHNT or Delixi
six.The gasoline burner:Nearby brand
eight.CZPT transmission chain:Dingsheng furnace industry generation
Tools installation, debugging and after sales services:
The expense of Set up, debugging and following-sales support in accordance with the discussion among two sides.At the exact same time, the supplier can have out technological direction by way of e-mail and video.
