Gas Patio Heater Regulator
If you're planning to warm inside the cold winter air with a propane patio heater, you need to know how to properly use the appliance. Matthew Griffith, chief of the prevention section of Montreal's Fire Department advises that consumers be looking for products that have safety certifications.
The patio heater must be properly attached and there should be no fire-prone material in the vicinity.
Pressure Regulator
Gas regulators are simple mechanical devices we drive through every day in our cars and homes without giving a second thought. Their invention, made 135 years ago, revolutionized the way propane and natural gas patio heater pyramid are used for cooking, heating, and welding with oxy-fuel. The fundamental role of regulators is exactly similar, but there are many variations. The regulator is based on an element that senses pressure, typically a dialythm made of fabric, to control a valve's location and limit the flow of gas.
The diaphragm connects to the stem of the valve using rods that run through the diaphragm and spring and finally into the valve. The gas pressure coming from the pipeline or from the house is sensed by this mechanism and it adjusts the position of the valve plug to align it to the demand of the house. As the gas consumption in the home decreases and the pressure decreases between the regulator and the 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 house grows, the valve opens further which increases the flow of gas.
The valve plug stays closed until the demand for the house decreases. The valve is then opened to increase the flow. This process, referred to as"sizing," is the basic operation of the regulator.
When the valve is opened, a pressure is built up in the main chamber of the regulator, which is connected to the outlet port of the hose by the venturi tube (see the image). This pressure is controlled by changing the screw or handle located on the exterior of the regulator. When the screw is rotated counterclockwise, it increases the pressure. When it is turned clockwise, it reduces the pressure.
When selecting a pressure regulator, remember that the maximum and minimum nominal pressures are established by commercial standards, not the pressure at the supply line. The regulator must also be compatible with the hose you choose to use. Find a hose marked whistle-free. It will feature alternating rings that are different sizes. This will stop resonant noises from building across the length.
Thermocouple
Thermocouples operate on the idea that two different metals that are in contact at one end create a voltage potential, even when they are at different temperatures. They are used to detect the temperature difference between two points in a system and convert this data into an electrical signal that can then be read by thermocouple meter or another instrument. Thermocouples offer a number of advantages over conventional sensors such as thermistors, which include the ability to detect extremely high temperatures and to function in corrosive environments.
The measuring (or hot) junction is created by connecting two metals with different properties at one end, while the other end, the reference (or cold) junction, is maintained at a constant temperature. Thermocouples create small voltages however, they're passive devices that don't require power to perform their functions. The voltage generated is proportional to the temperature difference between the measuring junction and the reference junction. The thermocouple manufacturers and organizations that offer metrology standards, like NIST offer reference tables for the function E (T). displaystyle scriptstyle e(T) for each specific thermocouple type.
There are three types of thermocouple connections: exposed grounded and weld. The exposed style of junction protrudes from the protective sheath, and provides the fastest response. A grounded thermocouple is recommended for measurements in corrosive environments. A thermocouple welded to a wire is physically isolated from the sheath using mgO powder to prevent penetration of moisture or gas that could lead to errors.
A thermocouple welded to a wire comes with the added benefit of being more resistant to vibration. It is recommended to use it in abrasive environments with pressures of up to 3000 psi. A thermocouple that has been damaged is usually the result of a lack in the polarity. If the sheath is not been properly polarized, both ends of the thermocouple might have different voltages at their junction for measurement. This can result in an inaccurate reading, or even damage the instrument. A sensor that is not properly calibrated or placed in the right place can cause a malfunctioning thermocouple.
Thermostat
In contrast to electric heaters that need to be hardwired into the wall gas patio gas heaters are portable and utilize natural gas patio heater gas or propane gas patio heater cylinders to fuel. Thermostats regulate the flow energy into these cylinders to ensure that they do not overflow, yet still provide warmth when required. The thermostat accomplishes this by measuring the temperature of air that is passing through it. The thermostat can also detect whether the room is at a temperature that is comfortable and turn off the heating.
The most commonly used type of thermostat is a digital one. It uses a microcontroller to convert an electrical resistance into an indication of temperature. It can do this much more accurately than older, mercury switch thermostats that utilized a mercury coil with three wires in it that would move depending on the temperature. This enabled it to tilt a mercury switch connected to the electrical circuit of the air conditioning or heater unit, turning it on or off.
Mechanical thermostats are another type. The thermostat is activated when the wax inside the small cylinder begins to melt, which is around 180 degrees F. (Different thermostats have different opening temperatures). When the wax is hot, a rod connected to the thermostat opens the valve. As the room cools the wax expands and the rod is pushed into the cylinder, closing the valve.
You can set thermostats to change the temperature at various time of the daytime. This can help you reduce energy consumption by setting your heating to go on and off when you are working or sleeping, instead of having it on continuously. You can also set the thermostat to come on earlier, so that your home will be an ideal temperature when you return from work or school. Thermostats usually include a feature called a heat anticipator, which stops the heater from coming on too early. This is because certain parts of the home reach the desired temperature before the thermostat.
Pilot Light
Although many modern heating and home systems have done away with pilot lights older furnaces and homes still use these devices to light the gas in the burner chamber. It's important to learn how to safely to relight the pilot light in case it ever goes out.
A pilot light generates a small flame that heats the thermocouple, which produces electricity and keeps the gas valve open. When the pilot flame stops, the thermocouple cools down and stops producing electricity, thereby closing the valve. Pilot lights are found on a majority of propane and natural gas appliances, including water heaters.
To relight a pilot light, you must first turn off the gas on the appliance. Then, you must remove any doors or panels that may be in the way of accessing the pilot light. Locate the pilot light tube, and follow the steps on the front of the appliance to open it. After you've lit the pilot light, return the knob on the pyramid gas patio heater valve to the "on" position.
The main reason to leave the pilot light on is for safety reasons. If you accidentally shut off the pilot light, the gas that is constantly venting out of the tube could build up in your home until an electric spark or static charge ignites the gas and causes an explosive explosion. To prevent this, the pilot tubes come with a built in cutoff valve.
A pilot light that is constantly burning is not just dangerous, but it also wastes energy. A pilot light can burn between $7 and $18 worth of gasoline every month, based on different studies. The wasted fuel creates a greater burden on the air conditioner during summer. Another concern with pilot lights is that it can attract spiders, who can spin webs that clog the pilot tubes. A constant flame can emit trace quantities of the compound Mercaptan that is responsible for the smell of rotten eggs in natural gas. If you're concerned about these problems, consider buying a remote controlled gas fireplace or replacing your old fireplace with a new, efficient model.
