gas patio heater regulator (reviews over at valuepunch49.bravejournal.net)
If you're looking to cozy with the cold outside with a propane patio heater, it's important to know how to properly make use of this device. Matthew Griffith, prevention section chief at Montreal's fire department, said shoppers should look for products that have safety certifications.
The patio heater should be properly attached and there shouldn't be any materials that could ignite nearby.
Pressure Regulator
Gas regulators are mechanical devices that we drive by every day in our vehicles and at home without giving them a second thought. Their invention, made 135 years ago changed the way natural gas and propane are used for cooking, heating and welding using oxyfuel. The basic function of regulators is similar, but there are many variations. The regulator is based on an element that senses pressure, typically a dialythm made of fabric, to regulate a valve plug's position and restrict the flow of gas.
The diaphragm is connected to the valve stem with rods that run through the set spring, over the diaphragm, and finally into the valve. The mechanism is able to detect the gas pressure in the home or pipeline and adjusts the valve plug's position to match the demand. As the use of gas in the house decreases, the pressure between the regulator and the house reduces too. The diaphragm expands downwards and the valve plug is moved closer to the orifice to limit the flow. As the demand for gas in the house increases the valve will open further which increases the flow of gas.
When the valve plug is closed it is held in position by the spring force until the demand from the house decreases, which then opens the valve to increase the flow. This process, also known as"sizing," is the primary operation of the regulator.
As the valve opens the pressure builds up in the main chamber of the regulator, which is connected to the hose outlet port by venturi tubes (see image). The pressure can be adjusted by adjusting the handle or screw located on the outside regulator. When the screw is turned counterclockwise it increases and decreases the pressure. When it is turned clockwise it reduces the pressure.
When selecting a pressure regulator be aware that the nominal maximum and minimum pressure is determined by commercial gas patio heaters standards, not the pressure of the gas in the supply line. The regulator must also be compatible with the hose you are using. Choose a hose which is labeled as whistle-free, with different sized rings that alternate to prevent resonant sounds from accumulating across the length of the hose.
Thermocouple
Thermocouples operate on the premise that metals of different composition in contact at their respective ends can generate the voltage even if they are operating at extremely different temperatures. They are used to identify the temperature differences between different points in the circuit and convert that information into an electronic signal that can be read by a thermocouple gauge or other instrument. Thermocouples have several advantages over conventional sensors, such as thermistors including the ability to measure extremely high temperatures and operate in harsh environments.
The measuring (or hot) junction is formed by joining two metals that are not compatible at one end, while at the other, the reference (or cold) junction, is kept at a constant temperature. Thermocouples are passive devices, meaning they do not require power to operate. The voltage generated is proportional to the temperature difference between the measuring junction and the reference junction. Thermocouple manufacturers and metrology standards organizations such as NIST provide tables of reference for the function E (T) displaystyle scriptstyle e(T) For each particular type of thermocouple.
There are three kinds of thermocouple connections: exposed, grounded and weld. The exposed type of junction protrudes from the protective sheath, and has the fastest response. For measurements in corrosive conditions it is recommended that a grounded thermocouple be used. A thermocouple that is welded is physically isolated from the sheath using mgO powder. This prevents moisture or gas from penetrating and causing errors.
The thermocouple welded wire is also a benefit in being more vibration resistant. It is recommended to use it in extreme environments that have pressures up to 3000 psi. A thermocouple that is damaged is usually due to the lack of the polarity. If the sheath hasn't been properly polarized, both ends of the thermocouple might have different voltages at their measurement junction. This can lead to an incorrect reading or damage the instrument. A sensor that is not properly calibrated or placed in the right place can also cause a faulty thermocouple.
Thermostat
Gas patio heaters unlike electric heaters which are hardwired to the wall are portable and run on natural gas or propane. Thermostats regulate flow of energy into these cylinders in order to ensure that they don't overflow, yet still provide warmth when required. The thermostat detects the temperature of air passing through it. The thermostat also detects when the room is cooling down to a comfortable level and turns off the heating.
The most commonly used type of thermostat is one that is digital. It uses a microcontroller to convert a changing electrical resistance into the temperature measurement. It can do this more accurately than the older mercury switch thermostats, which utilized an mercury coil with three wires inside that moved based on temperature. This allowed the thermostat to tilt the mercury switch that was connected to an electrical circuit to an air conditioner or heater by turning it off and on.
Another type of thermostat is one that's mechanical. It is tiny cylinders filled with wax that begins to melt at a certain temperature of perhaps 180 degrees F (different thermostats open up at different temperatures). When the wax is hot, a rod connected to the thermostat opens the valve. As the room cools down, the wax contracts and the rod is pushed into the cylinder to close the valve.
You can also program thermostats to change the temperature at different time of the daytime. You can cut down on energy consumption by setting your heating to turn on and off while you are working, or asleep, instead of having it on all the time. You can also set the thermostat to come on earlier so that your home is a comfortable temperature when you arrive back from work or school. Thermostats are also usually equipped with a feature called the heat anticipator that prevents the heater from turning off 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
Although many modern heating and home systems have eliminated pilot lights older furnaces and homes still rely on these devices to light gas in the burner chamber. If the pilot light is ever snuffed out, it's vital to know how to light it safely.
A pilot light generates small flames that warm a thermocouple, which generates electricity and holds the gas valve open. If the pilot flame ceases to burn the thermocouple cools and ceases to produce electricity, thus closing the gas valve. Pilot lights are utilized on the majority of propane and natural gas appliances, such as water heaters.
To relight the pilot, you first need to shut off the gas patio heater regulator in the appliance. The next step is to take out any doors or panels that could be blocking access to the pilot light. Follow the instructions on the front of the light to open the pilot light tube. Once you've switched off the pilot switch, turn the knob on the gas patio heater small valve to "on".
The main reason to leave a pilot light on is for safety reasons. If you accidentally shut off the pilot light, the gas that is constantly escaping from the tube could build up in your home until a spark or static electricity sparks the gas, causing an explosive explosion. To prevent this, the pilot tubes come with a built in cutoff valve.
A constantly burning pilot light is not only dangerous however, it also consumes energy. Numerous studies have revealed that a pilot lamp can burn between $7 and $18 of gas every month. This wasted fuel also places a heavier load on the air cooling system during summer time. Another concern with a pilot light is that it attracts spiders, which could spin webs that clog the pilot tubes. Additionally, a flame that is constant can release trace amounts of the mercaptan compound, which produces the rotten egg smell found in natural gas. If you're worried about these problems, consider purchasing a remote-controlled gas fireplace or replacing your fireplace with a more modern efficient and efficient model.
