Best Answer

As you use the tank, the pressure inside goes down. As the pressure drops, the temperature also drops because of something called the Ideal Gas Law (see the "Ideal Gas Law" Related Questions linked the left of this answer). Ice forms on the tank because water moisture in the atmosphere is condensed on the cold tank and then frozen.

Does PRESSURE in a propane tank without propane have any weight?

Very little. When using propane the liquid is constantly being converted to the vapor that is used. When the liquid that weighs $.24 pounds per gallon is gone the vapor will last only a short time.

How long will a 30000 btu convection heater last on a 20lb tank?

The MH80CV, part of the Mr. Heater Contractor Series, is a 30,000-80,000 BTU Propane Convection heater. The MH80CV provides reliable heat for areas up to 1900 sq. feet. It will operate for up to 14 hours on a 20-lb propane tank. The MH80CV features a standing pilot, piezo push-button ignition, and 'insta-lock' chamber for easy assembly. The MH80CV comes ready to use with the included hose and regulator. It operates on a 20-lb or larger propane tank (not included).There are a couple of other factors that may effect the time a 20 pound cylinder will last on a heater. Propane is stored in liquid form in the tank and must evaporate to be used in most heaters. The colder the temperature the propane tank is stored at the lower the pressure is in the tank. As the liquid propane evaporates it cools down the liquid propane still in the tank. As a result at minus -20 you might have a half full twenty pound tank and not have enough pressure to run the heater.

Can you sell a used propane tank?

There are many places that will buy used propane tanks. However, there are also places you can exchange the tank for a new one for a reduced price. If you use propane for grilling, it is cheaper to do a tank exchange then to sell the tank and buy a new one.

Does any brand of propane work for my new BBQ grill?

There is only one type of propane that can be used for your BBQ. If you go to any store that sells propane for BBQs you will be able to purchase a tank of propane. However since this is the first time you will be connecting your BBQ to a propane tank you have to make sure that you have the right fittings and hose to connect to the tank.


How Does a Propane Tank Work?

Propane fuel comes in either a liquid or gas form, and is used to power engines, gas torches, barbecue grills, portable stoves, and residential heating. You are probably most familiar with propane in tanks. Propane tanks are used for fuel in cooking on grills or camping stoves. The tank is normally 4.73 gallons, and is often referred to as a barbecue tank. The propane tank works by way of an attached metering nozzle device. Some rural homes or farms use larger propane tanks that are periodically refilled by propane-delivery trucks. These are common to homes or farms without convenient access to other energy sources. Larger residential propane tanks can be used to fuel furnaces, cooking stoves, water heaters, laundry dryers, grain dryers, and various heat-producing appliances around the home. Propane containers hold propane in its liquid form. Tanks use a series of standardized valves. These valves work together to ensure proper propane maintenance. The valves on a propane tank include a • Fill valve, which is used for attaching a delivery hose and refilling the propane tank. • Vapor return valve that functions to normalize pressure within the tank during propane delivery. • Service valve, which changes liquid gas propane into a vapor. • Relief valve that is used to release excess pressure and prevent volatile reactions. • Liquid withdraw valve, which controls the amount of LP gas that is released from the propane tank. In addition to these valves, two types of standardized gauges are essential to proper tank operation. A float gauge measures the amount of propane in the tank and a fixed liquid level gauge indicates when the propane level exceeds 80% of the tank’s total volume. Propane tank installation is a licensed trade, and only skilled individuals may install a propane storage tank. Professional propane workers ensure compliance with state regulations and safety to propane tank users. For larger tanks, a crane is often used for installing the propane container. A propane delivery driver will periodically return and refill a propane tank as it is needed. In addition, the driver is needed to recertify the tank for safety every 5 years, and to check environmental hazards.
