Gas Patio Heater Regulator
If you're planning to warm up in the cold outdoors with a propane patio heater, it's crucial to know how to properly use this appliance. Matthew Griffith, prevention section chief of Montreal's fire department, said that consumers should be looking for products that are safe to use.
It's also crucial to ensure that there aren't any combustible materials in the vicinity and that the patio heater is securely connected.
Pressure Regulator
Gas regulators are simple mechanical devices that we pass by daily in our cars and at home without giving them a second thought. Their invention, created 135 years ago, has revolutionized the way natural gas patio heater regulator and propane is used for cooking, heating and oxyfuel welding. The basic function of regulators is the same, however there are many variations. The regulator uses an element that senses pressure, typically a fabric-reinforced dialythm, to control a valve plug's position and restrict the flow of gas.
The diaphragm is linked to the valve stem with rods that go through the set spring, through the diaphragm and into the valve. The gas patio heater small pressure coming from the pipeline or from the house is sensed by this mechanism and it adjusts position of the valve plug to align it to the demand of the house. As the consumption of gas in the home decreases, so does the pressure between regulator and house. The diaphragm is deflated downward and the valve plug moves closer to the orifice in order to restrict the flow. As the demand for gas grows in the home the valve will open more, increasing the flow.
The valve plug is closed until the demand for the house decreases. This opens the valve to increase the flow. This process, also known as"sizing," is the basic operation of the regulator.
As the valve opens it creates pressure up in the main chamber of the regulator, which is attached to the outlet port of the hose with the venturi tube (see image). The pressure is controlled by changing the screw or handle located on the outside of the regulator. When the screw is turned counterclockwise, it increases and decreases the pressure. However, when it is turned clockwise it decreases the pressure.
When you are choosing a regulator for your pressure make sure to keep in mind that the minimum and maximum nominal pressures are determined by commercial standards and NOT the pressure at the supply line. The regulator should also be compatible with your hose. Find a hose marked whistle-free. It should have alternating rings with different sizes. This will prevent resonance noises from forming throughout the length.
Thermocouple
Thermocouples are based on the idea that different metals when in contact at their ends can generate the voltage even if they are at wildly different temperatures. They are used to determine the temperature differences between two points in a system and convert this information into an electrical signal that can then be read by thermocouple meters or any other instrument. Thermocouples are superior to other sensors, for instance thermistors. They can measure extremely high temperatures and operate in corrosive environments.
A pair of dissimilar metals are connected to one end of the sensor, forming the measuring (aka hot) junction, and the other end is kept at a constant temperature, also known as the reference (aka cold) junction. Thermocouples generate small voltages, however, they are passive devices that do not require power to perform their functions. The voltage produced is proportional to the temperature difference between the measuring junction and the reference junction. Thermocouple manufacturers and metrology standards organizations like NIST provide tables of reference for the function E (T) Displaystyle scriptstyle e(T) For each particular type of thermocouple.
There are three types of thermocouple connections: exposed, grounded and welded. The exposed type of junction extends out of the protective sheath and has the fastest response. For measurements in corrosive environments, a grounded thermocouple should be used. A thermocouple that is welded is physically insulated from the sheath using mgO powder to prevent the penetration of moisture or outdoor gas patio heater which could cause mistakes.
The thermocouple welded wire also has the added benefit of being more vibration resistant. It is recommended to use in harsh environments and with pressures as high as 3000 psi. If a thermocouple becomes damaged, it's usually caused due to a lack of the polarity. If the sheath is not been polarized, both ends of the thermocouple may have different voltages at their junction for measurement. This can lead to an incorrect reading or damage the instrument. A malfunctioning thermocouple could be caused by an improperly installed or calibrated sensor.
Thermostat
Gas patio heaters unlike electric heaters which are hardwired to the wall are portable and operate on propane or natural gas. Thermostats regulate flow of energy into these cylinders to ensure that they don't overflow, yet still provide warmth when required. The thermostat does this by sensing the temperature of the air that passes over it. The thermostat also detects when the room has been cooled to a comfortable temperature, and turns off the heating.
Digital thermostats are among the most commonly used. It utilizes a microcontroller in order to convert a fluctuating electrical resistance into an indication of temperature. It can do this more accurately than earlier mercury switch thermostats that utilized mercury coils that had three wires that would move depending on the temperature. This enabled the thermostat to tilt a mercury switch that was connected to an electrical circuit to a heater or air conditioner, turning it on and off.
A mechanical thermostat is another kind. It's a small cylinder filled with wax that begins to melt when it reaches a temperature, possibly 180 degrees F (different thermostats open at different temperatures). When the wax is hot, a rod that is connected to the thermostat opens the valve. As the room cools, the wax contracts and the rod gets pulled back into the cylinder, closing the valve.
There are thermostats that can be programmed to switch at different times during the day. You can save energy by programming your heating to switch off and on when you are working, or asleep, instead of being on all the time. You can also set the thermostat to come on earlier so that your home will be at a comfortable temperature when you return from work or school. Thermostats typically come with a feature known as a heat anticipator, which stops the heater from coming on too early. This is because parts of the house often attain the temperature set before the thermostat itself does.
Pilot Light
While many newer heating and homes have done away with pilot lights, older homes and furnaces still use these devices to ignite gas in the chamber for burning. It's important to learn how to safely relight the pilot light if it ever goes out.
A pilot light generates a small flame which heats the thermocouple. The thermocouple generates electricity and keeps the gas valve open. If the pilot flame goes out, the thermocouple cools and ceases to generate electricity, thus closing the gas valve. Pilot lights are utilized on a majority of propane and natural gas appliances, including water heaters.
Relighting a pilot light requires first that you shut off the gas valve on the appliance. Then, you must remove any doors or panels that might be blocking accessing the pilot light. Find the pilot light tube and carefully follow the procedure printed on the front of the appliance to open it. Once you've re-lit the pilot light, return the knob on the gas valve to the "on" position.
Safety is the main reason to keep a pilot light on. If you accidentally shut off the pilot light, gas that is constantly venting out of the tube could build up in your home until the spark or static electricity ignites the gas and triggers an explosive explosion. The tubes designed for pilots contain a built-in cutoff valve that can keep this from happening.
A constant burning pilot light is not only dangerous however, it also consumes energy. A pilot light can burn between $7 and $18 worth of gasoline each month, according to various studies. This waste of fuel also puts more strain on the air cooling system during summer time. Pilot lights can attract spiders which can spin webs and block the pilot tubes. A flame that is constant can release trace quantities of the compound Mercaptan which is responsible for the smell of rotten eggs in natural gas. If you are ever concerned about these issues, think about buying a remote-controlled gas fire or replacing a fireplace with a more efficient and modern design.
