Fuel supply system

Fuel lines should be mn where they will not be subject to high temperatures and must include protection with automatic and manual shut-off fire valves at the perimeter of the boiler house. Individual boilers should also be capable of isolation from this supply. Local requirements may vary on fuel supply systems, and these should be ascertained before installation. 

Although some integration has taken place where the appliance or boilermaker has assumed responsibility for the combustion system, overall, specialist manufacturers of combustion equipment who have developed products for each application such as boilers, furnaces, kilns and dryers, etc. serve the market. The burner makers have manufactured products which provide a packaged solution to the combustion requirement, looking after not just the burners and controls but also the fuel supply system, which may involve pumping, heating of the fuel, filtration and other peripheral equipment and functions. 

Engine additives were required in all gasoline to prevent deposits in engines and fuel supply systems. 

First generation biofuels are a direct substitute for fossil fuels in transport and can readily be integrated into fuel supply systems. They may also help prepare the way for further advanced developments, such as hydrogen. Although most biofuels are still more costly than fossil fuels their use is increasing in around... 

Use of CNG as a transport sector fuel requires investment in a dramatically different fuel supply system. Gas has to be taken from a gas distribution system, usually at a pressure of 0.3 to 1 MPa, and compressed to 20 MPa into vehicle CNG tanks. Without intermediate storage at the CNG vehicle Ailing station, a slow fill system is used that only has compressors. About 8 hours are required for refueling the vehicles. For a more rapid fill but usually no faster than 5 min, larger compressors and intermediate storage are required. 

Figure 16 LNG-to-CNG (LCNG) as applied to tank-filling stations. The LNG is pressurised to CNG pressure by pumping (200-300 bar) before vaporisation and filling of the car s tank. Alternatively when LNG is used as mobile fuel the pump and vaporising unit will become part of the car s fuel supply system.

Nearly 160,000 miles of high-voltage electrical transmission lines in the United States carry power from power stations to load centers (Edison Electric Institute, 2002). In addition, distribution lines carry the power from substations to end users. The electrical power system is fundamentally different from the liquid or gaseous fuel supply systems, which involve fluid flows that are relatively easy to direct and control. Electric power flow, which is dictated by complex physics principles, can often be difficult to control. 

The gas generated is burned in the combustion chambers and expands through the gas turbine, generating 4.2 MW of electricity. The gas turbine is a single-shaft industrial gas turbine. The fuel supply system, fiiel injectors and the combustors have been redesigned to suit the low calorific value gas (5 MJ/nm ). 

The oil was produced from non-contaminated soft wood from Spain. Due to the low pH-value, acid proof materials had to be used in the fuel supply system. The pure biooil need to be preheated up to 50 °C to achieve a sufficient viscosity. Bio-oil from pyrolysis contain considerable amount of water between 20 to 30 per cent. However, combustion in the gas turbine was not hampered by the presence of water as the ignition of the bio-oil was initiated by the pilot flame burning diesel fuel. 

The principal modifications involve the fuel handling and the fuel supply system, Basic results and insights of bio-oil combustion were obtained in the combustion test facility. 

Moreover, California s just-in-time motor vehicle fuel supply system is disrupted regularly because of upsets and breakdowns that occur at the few refineries that still operate in the state. The result is a fuel supply system that is as taut as a stretched rubber band. 

On the other hand, fuel supply system response (when hydrogen is stored in high pressure tanks) results intrinsically faster than air supply system. The dynamics of this last sub-system appear particularly significant for the evaluation of dynamic performance of an overall FCS [48], as air compressor response is the limiting step for an adequate response of stack to load requirement changes. In particular the variations in air flow rates have to guarantee instantaneous stoichiometric ratios always not much lower than 2 during fast accelerations [49]. 

As disadvantages compared to conventional fuels or synthetic liquid hydrocarbons, the low heating value has to be mentioned as well as the need to adapt combustion devices (materials, fuel supply systems). On the other hand, the environmental potential is obvious and the flexibility of the synthesis process with respect to product composition for different application fields seems to be promising. 

PFA Model 25 The Personal Fuel Appliance is on tour with the Ford Think fuel cell vehicle to demonstrate the household fuel supply system (Figure 4). 

The flame safefy system is critical to the safe opera-fion of fhe combusfion system. This may include some fype of flame scanner or flame rod to ensure either the burner or the pilot is operating. These are connected to the fuel supply system so fhaf fhe fuel flow will be stopped if fhe flame goes ouf to prevent a possible explosion for unreacfed fuel gases confacfing a hof surface somewhere in fhe combustor.
