furnace gas (3)(27) comprising a mixture of a part of the rich tail gas (8) and a part of the rich tail gas (8), and the low calorific value fuel (27) is heated to heat the high temperature furnace gas It is used and heated before it is injected into the blast furnace (1)....
Reconnect the electricity to the furnace. Turn up the thermostat until the furnace burners ignite. Check the gas pressure to make sure that the minimum pressure is 11 inches of water column. Turn off the electricity to the furnace and turn the main gas shutoff valve to the "Off" position....
>Trace the gas by using a methane and nitrogen mixture. Use a gas-detection instrument to measure the level of carbon monoxide (CO) that is in the supply air plenum, exhaust flue, or the area around the furnace. Check the pressure in the heat exchanger by using a magnehelic gauge test...
Machine vision has advanced immensely over the last decade, but Apple and Google’s map apps remain functionally illiterate when it comes to a big green sign at the top of an onramp to U.S. 50 eastbound from North Courthouse Road in Arlington. That sign’s message is reasonably simple com...

to freeze. The gas is much colder because there’s not enough of it to fill the coils; the gas over-expands inside the coils, resulting in lower pressure & lower temperature, hence freezing. TheJoule Thomson Effect(highly technical) describes the process. These N style evaporator coils are ...
On a typical gas furnace, the pilot light is a small gas flame that acts both as an ignition source for a larger burner within the furnace, as well as an indicator of whether your furnace is actually burning and producing heat. A pilot light going out can be inconvenient because it will...
“In simple terms, the compressor works by compressing the refrigerant gas, raising its temperature and pressure, and then circulating it through the system. This process allows the HVAC system to remove heat from indoor air (in cooling mode) or absorb heat from outdoor air (in heating mode)...
The silver fan control dial shown in our photograph, driven by a bimetallic spring that is inside the probe that is in turn inserted into the supply air plenum, responds to temperatures inside the furnace. In response to supply air temperature this control turns the blower fan on, off, and...
or direct rebates off the sticker price of a heat pump. to find out what's available in your state, check with your utility company or the state government's website. a quick search for programs in your state might turn up even more discounts you can apply to a heat pump....
