Furnace burner tubing and pipe how to install

Tubing need a fuel supply system, piping is provided with a filter, control valves, check valves, valves, high and low pressure switches, shut-off valve,Safety Valve and then into the burner, the former mouth requirements for hose connection.
Trachea into gas and air, if the air is the combustion air blower, soft connection, low pressure switch, then hose into the burner.
Burner is the fuel and air mixture combustion discharged in a certain way means collectively.
Burners by type and application areas divided industrial burners, burner, civil burners, several special burner.
Industrial burners known burner, many types of specifications type, there are oil, gas, coal and several major categories. Applications is very broad, requiring fuel combustion to heat the material or the reaction of industrial applications need to use the burner.
Burner, also known as integrated burner to oil and gas-based. General application in small and medium-fuel boilers, fuel hot air oven and small fuel furnace.

Stable combustion burner "What does that mean?

Efficiency of the boiler rated load / boiler / burner environmental correction coefficient determines the power of choice of the gas burner. Power agas Burner Valves range is a gas valvemodel set later, after certain allowable gas pressure, corresponds to a flow rate range, and the greater the gas pressure, the greater the flow. Visible: the burner can be equipped with different valve, with a valve flow at different gas pressures also different boiler rated load, environmental and boiler efficiency decisions burner power, gas flow decided burner power. Set the gas flow in gas pressure determined, you can select the appropriate gas valve, the gas valve at the gas pressure must be covered and larger than the traffic. "Gas train gas mass flow should enable the boiler operation at rated load, stable combustion burner," what it means.

Gas Burner Valves action principle

gas Burner Valves action principle

The gas coming from the direction of the first one is the gas safety valves, the second is operated valve, double solenoid valve is to set up a double insurance, in case of a solenoid valve leak, and there is another to ensure that does not leak. To ensure this, there are no two solenoid valves are bad, the actual operation between the two solenoid valves is also equipped with leak detectors, once there is a valve leak, burner can not open the solenoid valve, and thus not start burner, the solenoid valve must be repaired or replaced, ensure two solenoid valves do not leak before starting the burner.

Ignition failure

Gas water heater ignition pulse ignition firing pin but not the main burner ignition failure:
Low battery 1. The gas water heater or battery connection is bad.
2. hot gas water heater switch is bad.
3. The Water Heater Gas Valves is bad or there is the phenomenon of the card.
4 .. gas water heater circuit board has contact failure or damage phenomenon.
5. insufficient water pressure or water pressure micro switch bad.
6. above the fault can not be excluded, please professional maintenance personnel to repair or service call to repair.

It is to shut off the gas stove gas tank valve or the first main valve?

First off gas gas stove valves, then close the main gas tank valve!
Stove tempering problem mostly occurs on artificial gas (gas) stove (liquefied petroleum gas, natural gas stove safety tempering phenomenon is rare). Artificial gas stove and no valve. Tempering: When the speed of the gas leaving the fire hole is less than the burning speed, the flame will be retracted into the fire hole inside, resulting in a mixture in the combustion burner, heating, undermine the primary air ejector, and the formation of incomplete combustion. Tempering will destroy combustion stability, and easy to damage the stove.
Tempered with a degree preheated air coefficient, gas source nature, components and gas-air mixture, the fire hole diameter, fire orifice discharge velocity.

How to adjust the valves on the gas stove

1, the principle of the two intake gas valve is to control the air volume, helps regulate the fire burning.
2, if you turn off two Gas Valves, no air enters the combustion, the flame will be extinguished or incomplete combustion waste gas source.
If the valve is adjusted to the maximum amount of wind caused by bad Assembly source of ignition and gas waste.
3, such as a close one on, two out of the ring of fire because the stove, close, and open a case with the previous combustion occurs.
4, adjusting the good will leak but there will be inadequate combustion waste gas source, adjust the flame when you use the color blue fire better.

Burner maintenance

(1) Regularly clean worrying too much.
(2) to maintain a sense of photoelectric eyes clean.
(3) at regular intervals, cleaning the interior of the burner.
(4) near the burner temperature should not be too high, otherwise it will affect the normal operation or damage to the burner means, especially damage to the control box.
Nearby (5) the burner should be kept clean, can not place flammable debris.
(6) some components unstable voltage will cause damage to the burner.
(7) to avoid the burner is water splashes.
  (8) regularly check the gas Burner Valves, After the gas safety burner valve used remember to turn off.

Large flange standard in Europe and the United States

The DN1500 DN2000 Flange European standards in the Americas, but there is no standard, reflecting the maximum size of. hose adaptersAlthough the material is the same, but the standards are different, whether it is in the form of a bolt hole and the sealing surface and the theoretical weight is different. The European system 20593 and 20595 specifications are the same, but the rough 20601 standard is the same, because of what, what kind of support system, large flange blind flange.hydraulic adaptors

How to control the noise of stove valve

The cavitation bubbles within the contact surface with bubbles isolating stove valve and hardened valve and seat surface will be the impact of cavitation, while adding body outlet bushing in place to protect the bullied eclipse the impact site. stove valves at the outlet bushing plus body as a supplement designed to prevent the liquid collision in the top burner valve  body wall, protecting the valve by scouring the site, at the same time weaken some noise.
Plus silencer to the partial pressure of the burner safety valve and sub-noise. This approach is essentially the cavitation condition into a flash conditions to deal with, so applications need to simultaneously trim do to protect hardened Gas Burner Safety Valve.
