If you're planning to warm up in the cold outdoors with a propane patio heater, you need to understand how to make use of this device. Matthew Griffith, chief of the prevention section of Montreal's Fire Department advises that consumers look for products that have safety certifications.
The patio heater needs to be securely attached and there should be no materials that could ignite nearby.
Pressure Regulator
Gas regulators are mechanical devices that we drive by every day in our vehicles and homes without a second thought. Their invention, 135 years ago, has changed the method in which propane and natural gas are used for heating, cooking, and welding with oxy-fuel. There are many variations in the design of regulators however their primary purpose is the same. The regulator utilizes a pressure sensing element, often a fabric-reinforced diaphragm, to control the position of a valve plug and limit the flow of gas.
The diaphragm connects to the stem of the valve with rod that runs through the diaphragm and spring, then into the valve. This mechanism detects garden gas patio heater pressure in the house or pipeline and adjusts the valve plug's position to meet the demand. As the consumption of gas in the home decreases and the pressure decreases between regulator and house. The diaphragm expands downwards and the valve plug moves closer to the orifice in order to limit the flow. As the demand in the home increases, the valve opens further and increases the flow of gas.
When the valve plug is closed it is held in place by the set spring force until the demand of the house drops, which opens the valve to increase the flow. This process is called sizing and it is the primary function of the regulator.
When the valve is opened it creates pressure in the main chamber, which is connected to the outlet port of the hose via a venturi tube. This pressure is regulated by adjusting a screw or handle located on the exterior of the regulator. When the screw is turned counterclockwise it increases and decreases the pressure. However, when it is turned clockwise, it reduces the pressure.
When selecting a pressure regulator be aware that the maximum and minimum nominal pressure is set by commercial standards and not the pressure of the gas in the supply line. The regulator must also be compatible with the hose. Look for a hose that is labeled as whistle-free, that has various sizes of rings to prevent resonant sound from accumulating across the length of the hose.
Thermocouple
Thermocouples are based on the concept that two different metals that are in contact at one end generate a voltage potential, even when they are at extremely different temperatures. They are used to measure the temperature difference between two points in a system and transform this information into an electrical signal that can then be read by a thermocouple meter or other instrument. Thermocouples have several advantages over more common sensors such as thermistors, which include the ability to detect extremely high temperatures and to function in environments that are corrosive.
The measuring (or hot) junction is created by connecting two metals with different properties at one end, and the other end, the reference (or cold) junction, is maintained at a constant temperature. Thermocouples are passive devices which means that they don't require power in order to function. The voltage produced is proportional to the difference in temperature between the measuring and reference junctions. Thermocouple manufacturers as well as metrology standards organizations such as NIST provide tables of reference for the function E (T) displaystyle scriptstyle e(T) for each type of thermocouple.
There are three types of thermocouple junctions- an exposed, grounded, and wire that is welded. The exposed type of junction is a bit higher than the protective sheath, and provides the fastest response time. For measurements in corrosive environments the thermocouple must be grounded. be used. A thermocouple welded-wire is physically isolated from its sheath using mgO powder. This stops gas or moisture from entering and causing errors.
A thermocouple that is welded has the added benefit of being more resistant to vibration. It is recommended to use it in extreme environments with pressures of up to 3000 psi. A thermocouple that has been damaged is usually caused by a lack in polarity. If the sheath has not been correctly polarized, the two ends of the thermocouple could have different voltages at their measurement junction. This can lead to an inaccurate reading, or even damage the instrument. A faulty thermocouple can also be caused by an improperly calibrated or installed sensor.
Thermostat
In contrast to electric heaters that need to be wired directly into the wall gas Garden patio heater Gas heaters are portable and utilize propane or natural gas cylinders for fuel. Thermostats control the flow of energy to these cylinders so they don't spill over, however they can still provide heat when required. The thermostat detects the temperature of air passing through it. The thermostat also can tell when the room is at a temperature that is comfortable and turns off the heating.
Digital thermostats are among the most commonly used. It makes use of a microcontroller to convert an electrical resistivity into an indication of temperature. It can perform this task more accurately than the older mercury switch thermostats that used mercury coils with three wires inside that would change according to temperature. This enabled the thermostat to tilt the mercury switch that was connected to an electrical circuit that was used to power a heater or air conditioner by turning it off and on.
Another type of thermostat is one that's mechanical. It is tiny cylinders filled with wax that starts to melt at a temperature that is perhaps 180 degrees F (different thermostats open up 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 shrinks and the rod is pulled into the cylinder to close the valve.
You can set thermostats to change the temperature at various times during the daytime. This can help you conserve energy by setting your heating to go on and off when you are at work or asleep, instead of having it on constantly. You can also set the thermostat to turn on earlier so that your home will be a comfortable temperature when you arrive back from school or work. Thermostats often include a feature called a heat anticipator, which stops the heating system from turning on too early. This is due to the fact that different areas of the house often attain the temperature set before the thermostat itself.
Pilot Light
While many modern homes and heating systems have eliminated pilot lights older furnaces and homes still rely on these devices to light gas in the burner chamber. It's important to learn how to safely restart the pilot light if it ever goes out.
A pilot light creates tiny flames that heat the thermocouple. The thermocouple produces electricity, and keeps the gas valve open. When the pilot flame stops, the thermocouple cools down and stops producing electricity, closing the valve. Pilot lights are found in a wide range of propane- and natural gas-powered appliances, such as water heaters, fireplaces, furnaces, ranges, barbecues and hot tubs.
The process of lighting a pilot light requires first that you shut off the gas valve at the appliance. The next step is to remove any panels or doors that might be blocking access to the pilot light. Locate the pilot light tube and follow the steps on the front of the appliance for opening it. Once you've switched off the pilot, turn the knob of the gas valve back to "on".
Safety is the main reason for leaving a pilot light lit. If you accidentally turn off the pilot light, gas that is constantly escaping from the tube could accumulate in your home until a spark or static electricity ignites the gas and triggers an explosive explosion. To prevent this from happening, the pilot tubes come with a built in cutoff valve.
Aside from the safety concerns that a burning pilot light is also an enormous amount of energy. The pilot light consumes between $7 and $18 worth of gasoline per month, according to various studies. The wasted fuel is a bigger burden on the air conditioner in the summer. Pilot lights can attract spiders which can spin webs, and clog up the pilot tubes. A constant flame can emit small amounts of the compound Mercaptan, which is the cause of the smell of rotten eggs that is common in natural gas. If you're worried about these issues, think about purchasing a remote-controlled gas fire or replacing your fireplace with a new, efficient model.
