Can you convert pipe natural gas central heating to bottle lpg central heating?
You will need new injectors on the boiler and some additional controls on the gas line. Pipework for LPG is smaller than nat gas so your pipes should be fine.
How do you prevent boiler explosion?
All boilers are made to a pressure specification and in most countries any pressure vessel over a certain size is required to be periodically inspected and pressure tested to ensure it is fit for purpose. In addition to being in sound condition, the boiler is also expected to have some form of pressure relief valve. This is of sufficient size to vent off excess pressure before it gets to an explosive situation. It is obviously important that the pressure of this device is set to a lower level than the ultimate pressure specification of the boiler. Even quite small boilers, like those in coffee makers need to be inspected. Some boilers are 'gas fired' such as home heating boilers. These have a device called a thermocouple that detects the flame and is linked to the gas valve. If the flame goes out, or the burner does not ignite when gas is released in the boiler, it will shut the gas off. Typically gas fired boilers have a number of devices that will shut off the gas in the event that something doesn't work. This means that if the gas supply pipe is in sound condition, the boiler itself cannot leak gas and cause an explosion.
What is an application of flue gas?
About the most common application of flue gas is as a heat source. Recall that flue gas is the stack gas from plants fired with combustibles (coal, oil, gas, biomass, etc.), and it exhausts into the atmosphere. We spend a lot of money monitoring stack gas to keep the combustion process as tightly controlled as possible. That minimized emissions. The heat in the stack gas can be used to heat water or the like, and the preheated water can then be fed back into the boilers to create the steam that drives the turbines that generate electric power (which is one example, but a common one). The heating of the (boiler) feedwater with the flue gas increases the efficiency of the whole operation. It's classic steam cycle power generation, and the preheating of feedwater within the stack (by the flue gas) is a time-proven tactic to reduce costs.
What can blast furnace waste slag be used for?
its used a fuel , but has less calorific value as the carbon monoxide percentage is less which is the main combustible gas in the b.f gas. its used in heating the blast of hot air in the blast furnance itself and also can be used in rolling mill, sinter plant, and many more where you need heating
What is supercritical boiler?
The following extract taken from an article by Ingo Paul in Energy Issues No 19 April 1999 published by the World Bank [external link] briefly describes the difference between a subcritical and a supercritical boiler. "Supercritical" is a thermodynamic expression describing the state of a substance where there is no clear distinction between the liquid and the gaseous phase (i.e. they are a homogenous fluid). Water reaches this state at a pressure above 22.1 megapascals (MPa) The "efficiency" of the thermodynamic process of a coal fired power (sic) describes how much of the energy fed into the cycle is converted into electrical energy. The greater the output of electrical energy for a given amount of energy input, the higher the efficiency. If the energy input to the cycle is kept constant, the output can be increased by selecting elevated pressures and temperatures for the water-steam cycle. Up to an operating pressure of around 19 MPa in the evaporator part of the boiler, the cycle is sub-critical. This means, that there is a non-homogeneous mixture of water and steam in the evaporator part of the boiler. In this case a drum-type boiler is used because the steam needs to be separated from water in the drum of the boiler before it is superheated and led into the turbine. Above an operating pressure of 22.1 MPa in the evaporator part of the boiler, the cycle is supercritical. The cycle medium is a single phase fluid with homogeneous properties and there is no need to separate steam from water in a drum. Once-through boilers are therefore used in supercritical cycles. www.whizkris.com
What companies do boiler installations nationwide?
The most relevant company that does boiler installations nationwide is Norther Gas and Heating. From full Gas Central Heating Systems to replacement Condensing Boilers and Combi boilers. All our boilers are 'A' rated energy efficient boilers.
What is the function of a central heating engineer?
A central heating engineer installs heating systems. They are also known as gas engineers. They fit, service, and repair boilers and heating systems that have broken down.
What do most homes use for heating?
Gas boilers.
What is natural gas used for today?
heating boilers, gas cookers
Where can one find rates on British gas and central heating prices?
British Gas has a website where they publish rates on gas and central heating. They also offer information on how to get a unit installed, and other options for heating and cooling your home.
How does oil central heating compare to gas central heating?
Oil central heating tends to be more expensive when compared to gas central heating as the price for heating oil tends to be higher when compared to natural gas. The price of heating oil also tends to be more volatile than natural gas.
What is an alternative to a gas boiler when a person is looking at furnaces?
Electric heating boilers can be a useful alternative to gas and other conventional furnaces. LPG and oil-fired boilers are also very efficient. Biomass boilers are also becoming popular.
What is cheaper for electric usage radiators or central heating?
The cheapest option between electric, radiators and central heating is Gas Central Heating. The reason that gas is cheaper than electric is because electricity costs 4-6 times more than gas.
What types of boilers does Vaillant produce?
Vaillant is one of the greatest heating manufacturers in the UK. The produce gas boilers. They are really energy-efficient and many people use them all around the world.
Disadvantages of oil boilers?
The main disadvantage of oil boilers is cost right now. Home heating oil is significnatly more expensive than gas right now. There is no increase risk of fire.
What are the uses of bio-gas plant?
1. Biogas can be substituted for natural gas or propane as fuel for boilers and electrical generators. Excess biogas should be flared for safety and odor control. 2. Cooking 3. Space heating; water heating; and process heating
