Gas stoves common problems and solutions

1 Q: flameout protection device with the ignition stoves Why stay for some time when you need more
A: flameout protection device is fixed on the cover next to a gas thermocouple to feel the heat of the outside world changes , to ensure that the case of unexpected flameout , gas stove can automatically cut off the gas source, to ensure personal safety . Gas thermocouple flameout protection has two aspects, on the one hand , he flameout protection case in a very short period of time cut off gas supply , on the other hand , the ignition , the thermocouple only feel some heat outside to the ventilation pipe flow, international regulations this time is 4.5 seconds .

2 , Q: liquefied petroleum gas juh hours what measures should be taken

A: The normal LPG gas stove flame was blue , clear flame inside the flame height of about 20mm, there is a slight noise , strong firepower . If there is a small fire , its causes and remedies are as follows:

1 ) , the burner fire cover fire hole clogged by dirt , mixed gas burner outflow obstruction , clearing fire hole dirt.

2 ) , nozzle clogging , unscrew the nozzle clean .

3 ) , the regulator inlet and the nozzle is clogged rust , hinder the gas outflow of bottle body , the replacement of qualified regulator .

4 ) , fold flat vent hose blocked Lee straight hose .

5 ) , in addition to the gas to be used is completed, the valve is not open all the other reasons we should pay attention , you can take appropriate action to resolve .

3 Q: Users in the daily process of cooking soups often overflow extinguish the flame of the phenomenon, then there will be misfire phenomenon, how to deal with

A : Because the main ignition needle damp due. This time do not give up because they can not use the automatic ignition . Please use matches or lighters ignition , gas stove burning end of normal time, remove the ignition needle can be auto-ignition of moisture .

4 , Q: gas stove in the course why yellow flame or black smoke  How should exclude

A: The yellow flame of a gas flame incomplete combustion , flame reddish yellow fire burning seems very busy , in fact, soft and weak flames , thermal efficiency is very low , and to pot coke, not only a waste of gas , and will cause air pollution.

1 ) , if it is caused by the amount of air is too small yellow fire live black smoke, adjustable throttle , the throttle opening larger.

2 ) , if it is temperament causes yellow fire or black smoke , replaceable temperament.

3 ) If the ejector chamber , the nozzle of a foreign body can also cause fire or gas stove with yellow black smoke , should foreign body removal.

5, Q: gas stove fire is normal  Gas stoves Why is there fire

A: gas stove fire was caused by:

1 ) , gas Cause : When the combustion gases or impurities within the water more too , makes flame color rendering booming.

2 ) , dust Cause: When the house when cooking with dust or moisture in the air increases the amount of oil and gas , are also prone to fire .

3 ) , throttle Cause : When the damper adjustment is poor, such a situation may also occur , then, can only damper .

4 ) , supporting pot rack reasons: Because supporting surface enamel pot rack color red heating at high temperatures , because of the special material enamel pot racks around the branch will find the flame is red, which is the color of the metal ions at high temperatures .

Therefore, when fire is not burning stove there is a problem , but rather caused by the above reasons , will not affect the normal use , it would not harm human health .

6, Q: If there is a phenomenon off the fire from the flame , how to troubleshoot

A: 1 ) If the gas pressure is too high ( generally occurs in the gas valve failure ) resulting from the fire , with a U-shaped manometer check outlet pressure can be adjusted to the same plate ;

2 ) , if the stove surrounded by wind, reducing the ambient air flow ;

3 ) , the required gas stove temperament and temperament does not match the use of gas from the flame from the fire caused by the need to change the temperament , so that they match ;

4 ) , caused by excessive intake air from the flame , the fire off , adjust the throttle to reduce the amount of wind can be.

7 , Q: What is off the fire  Appeared off the fire should be how to do

Answer: from the fire is due to the inlet gas pressure is too high or too large, resulting in combustion flame drifted away from fire cover . Appeared from the fire should first instruct the user to correctly adjust air flow adjustment damper at small ; another valve overhaul the user's home , if the natural or artificial gas, caused by excessive pressure in the pipeline , companies are required to supply feedback to solve .

8, Q : flameout protection device with a gas stove works is what  Use should pay attention to what matters

A: Currently, the world's more popular off protection is thermocouple , its working principle is the thermocouple is heated, it will generate thermoelectric power, the solenoid valve can work potential . Specific gas stove works as follows: When you press the knob , a small fire ignited, by its flame heating the thermocouple , thermoelectric power generation . Thermoelectric power through the wires into the electromagnetic coil to generate a magnetic field pull the solenoid valve , gas valve is open, open burning pathways to maintain its normal combustion in the event of high winds or other spill soup , extinguish the flame , the thermocouple thermoelectric power drops quickly to zero , the coil de-energized , the solenoid valve fails , reset rapidly under the action of the spring , the valve closes the gas path , terminate gas supply , and ensure safety .

Stove thermocouple protection device should be taken to keep the thermocouple and the distance between the fire cover . Generally speaking, the thermocouple height should be basically the same height with fire cover , tolerance of 1 (+ -) 0.5mm, thermocouple and fire cover distance can not be too far away, is generally maintained at 4 (+ -) 0.5mm distance from the most good, if the installation location is too low, insufficient heat the thermocouple to generate thermoelectric power is not enough, do not pull the solenoid valve , the installation location is too high, the flames touch too easy to burn thermocouple, the same way, too far, too will thermoelectric power is not enough, does not make the solenoid valve opens .

9, Q : When faced with gas stove when you beat the fire has been how to do

A: If you experience gas stove has beat the fire , the following procedures shall be checked : First , check whether the switch in the open air source state, if at open state, then secondly , check the connection hoses fold flat or bent , if not fold flat or bent , then finally , pick up branches pot rack , see whether flaming ignition nozzle :

1 ) , if you do not get angry , then see whether the discharge needle discharge : a, if the discharge needle does not discharge , indicating that the discharge needle failure , replace the discharge needle . b, if the discharge needle discharge , indicating a valve malfunction , replace the valve.

2 ) If the sparkle : a, if normal combustion , indicating a high position igniter , igniter should guide the user to press down gently a few, can be put on supporting pot rack . b, if irritated , but the flame is too weak, not up at the stove , it is the gas pressure is too low , gas stove users recommend their replacement valve, coal gas and natural gas companies should be to reflect . c, if you get angry , and the flame can reach fire cover place, but that is not on fire , that is the valve plug guide users with thin wire to clear the nozzle .

10 , Q: What is tempering  Gas stove why there is tempering

A: Tempering refers to the burner flame inside even throttle office, and is often associated with "bite bite ", " hastily " burning sound ; if not promptly detect and stop , it may cause burning stove burned body surface or the emergence tempering, for two reasons:

Cause a fire hole blocking . The gas will be some different levels of impurities ( such as sulfur ) , gas stoves use a long time , the fire will cover the fire hole in the dirt in precipitation , the fire hole smaller, if oppression gust or overflow , causing flames to back, then there tempering, in order to avoid this situation , use for some time to clean up fire hole .

Reason 2 , the burner is not reclosable or throttle into the wind at large, are also prone to temper . Therefore , when there is tempering , proper handling procedures are:

 observe whether the fire hole blocked ;

 Check fire cover placement is in place ;

 damper .

11, Q : gas stove damper in what place  Does it do

A: hand hold gas stove , the burner nozzle junction has two iron plates loaded with handles , one adjustable small fire , and another fire regulation ; They are close to the burner through the spring , gently toggle lever , can adjust the size of the hole into the wind , thus changing the state of the flame . When the combustion conditions are not ideal , such as yellow fire, black fire , the flame is too large or too small, or if combustion noise , tempering phenomenon, by adjusting the throttle into the wind at the size of the amount needed to achieve the ideal combustion conditions .
