DESC:FIELD OF THE INVENTION
This invention relates to a Generator for Floating Cranes. Specifically, the generator is an alternative to a preexisting diesel generator, using an alternative source of energy to generate power to operate the engines of Floating Crane.
BACKGROUND OF THE INVENTION
In a world facing ever-increasing environmental and financial challenges there exist a growing need for more fuel-efficient sea-going vessels. Many of these vessels are multipurpose, performing a wide variety of tasks. A flexible vessel configuration is required to maintain optimal energy efficiency regardless of operating mode.
Conventional diesel-mechanical and diesel-electric propulsion systems both have their advantages and disadvantages. Combining the best of both propulsion systems and making a hybrid propulsion system is already a reality. Hybrid propulsion systems are becoming increasingly popular when choosing propulsion systems for new vessels for saving fuel and reducing the emission of NOx, CO2, and other hazardous emissions.
Diesel engines present unique challenges relative to emissions including a need to simultaneously limit emissions to the environment of so-called criteria emissions including NOx, particulates, hydrocarbons, and CO, as well as limit other emissions including CO2 while also meeting performance requirements. Emissions standards typically require engine output to meet a defined schedule of output shaft torque and speed requirements which simulate a broad range of operating conditions encountered in real-world operation.
Diesel currently marketed in India is of two grades: High-Speed Diesel (HSD) and Light diesel oil (LDO). The former is a 100% distillate fuel while the latter is a blend of distillate fuel with a small proportion of residual fuel. HSD is normally used as a fuel for high-speed diesel engines operating above 750 rpm such as buses, lorries, generating sets, locomotives, pumping sets, etc. Gas turbines requiring distillate fuels normally make use of HSD as fuel. LDO is heavier than diesel oil and is mostly used in furnaces or for power generation. Furnace oil (FO) is another fuel known for power generation and is heavier than diesel oil like LDO. Furnace oil is a fraction obtained from petroleum distillation. LDO has a typical density of over 920 kg/M3 and FO has a typical density of over 970 kg/m3, while diesel has a lower density in the range of 845 kg/M3. Diesel is mainly used in a combustion engine.
Light diesel oil (LDO) & Furnace oil is the residual petroleum products and hydrocarbons. All the impurities and metal content of petroleum are concentrated in these products have many different industrial hitting applications.
LDO is a blend of distillate fuel with a small proportion of residual fuel. The average chemical formula for common diesel fuel is C12H23, ranging approximately from C10H20 to C15H28. LDO consists of the above structure with blends of vegetable oil or lipids. b. Furnace Oil: Furnace oil is a Dark, viscous residual fuel oil which is obtained by blending residual products from various refining processes with suitable diluents usually middle distillates to obtain the required fuel oil grades.
LDO, also known as “residual fuel oil”, is based on the high viscosity, tarlike mass, which remains after the distillation and subsequent cracking of crude oil to produce lighter hydrocarbon products, such as petrol, distillate diesel fuels, and heating oil or feedstock for lubricants.
The main components are alkanes, cycloalkanes, and different carbon hydrides. The boiling range is between 300°C and ~700°C. Due to its semifluid consistency, LDO has to be preheated to make it combustible in engines.
Light Diesel Oil is a type of diesel fuel that has flash point greater than 66 °C & is mainly used in stationary applications. LDO is a non–automotive diesel fuel used mainly in low RPM engines and Equipment. It has also been widely used in certain types of boilers and furnaces as basic fuel.
LDO is used in medium and slow speed diesel engines operating below 750 rpm employed in earth moving equipment, pump sets, power generation, marine engines, industrial application, heating purposes, etc. The LDO Marketed in India confirms to IS 1460:2000 and amendment No.2 April 2003 Specifications for LDO.
Furnace oil (FO) is one of the cheapest fuels available for industrial use. It is a by-product of petroleum refineries. While processing the CRUD Oil, FO is one of the products along with other petroleum fuels like HSD, Petrol etc. Typically it has a calorific value as 10000 cal/gm. The furnaces which are used mainly for heating or pre-heating a large quantity of metal, are the main users of FO. It is used primarily for steam boilers in power plants, aboard ships, and in industrial plants.
FO is a dark viscous residual fuel obtained by blending mainly heavier components from crude distillation unit. As per IS 1593:2018 specification, Furnace Oil is classified into four grades – LV, MV1, MV2 and HV. FO falls under the category of Class C, under PESO classification. FO is mainly used as a Fuel for slow-speed engines operating below 750 rpm for captive power generation.
Presently, an independent diesel engine generator is extensively used on a ship, which costs much light diesel each year. If we can make full use of the main motor of a ship to generate power via a shaft, then much energy and fare can be saved.
A floating crane is type of sea vessel that has a crane mounted on it. The earliest floating crane designs were no more than old ships converted to include a large crane mounted on the deck. Later, purpose built, catamaran and semi-submersible designs replaced these converted mono-hulls due mainly to increase lifting capacity and improved stability.
Floating Cranes are often used for constructing ports and bridges. They are useful for loading and unloading heavy items to and from ships. They are also used for transferring equipment from one vessel or platform to another, moving around equipment on the sea deck, and recovering or placing equipment on the seabed.
Floating cranes are mainly of two types i.e. Dumb Crane Barge and Self-propelled Crane barge. Floating cranes are used at anchorage and at ports where there is draught restriction to load/unload dry bulk cargo from a gearless vessel of various types such as Panamax, Cape, and Baby Cape vessels. All around the world Floating cranes operate on Diesel as fuel for its functioning.
OBJECTIVE OF THE INVENTION
Looking at the current scenario prevailing in India and the economic slowdown, competition and cost-effectiveness are two primary factors influencing business sustainability and development. To factor in these primary influences, bringing down/lowering the operational costs is of prime importance.
The objective of the invention is to utilize Fuel oil as an alternative to diesel as a source of energy to generate power to operate the engines Floating Crane. The term Fuel Oil for the explanation the present invention include both LDO and FO. It is the cheapest liquid and most easily available fuel.
This concept of using Fuel oil as an alternative source of energy to diesel is already known around the world. However, it is for the first time that this concept has been successfully implemented in the Diesel Generator of a Floating Crane.

According to the present invention the working principle of the present invention has been described in brief. The System operates on the lean- burn principle the mixture of air and gas in the cylinder has more air than is needed for complete combustion. Lean combustion reduces peak temperatures and therefore NOX emissions.
A lean burn mode is a way to reduce throttling losses. An engine in a typical vehicle is sized for providing the power desired for acceleration but must operate well below that point in normal steady-speed operation. Ordinarily, the power is cut by partially closing a throttle. However, the extra work done in pumping air through the throttle reduces efficiency. If the fuel/air ratio is reduced, then lower power can be achieved with the throttle closer to fully open, and the efficiency during normal driving (below the maximum torque capability of the engine) can be higher.
The engines designed for lean-burning can employ higher compression ratios and thus provide better performance, efficient fuel use and low exhaust hydrocarbon emissions than those found in conventional gasoline engines. Ultra-lean mixtures with very high air–fuel ratios can only be achieved by direct injection engines.
The main drawback of lean-burning is that a complex catalytic converter system is required to reduce NOx emissions. Lean-burn engines do not work well with modern 3- way catalytic converter which require a pollutant balance at the exhaust port so they can carry out oxidation and reduction reactions so most modern engines tend to cruise and coast down at or near the stoichiometric point.
In the embodiment described herein according to the present invention the combustion chamber of main diesel generator works on the 4- Strokes system comprising of:
Suction Stroke- In this stroke, the piston moves from the TDC (Top) to BDC (Bottom) which makes pressure difference in the combustion chamber. This leads to the intake of air. In contrast to this, the charge (fuel oil and air) is admitted.
Compression stroke- In this stage, the air inside the chamber is compressed by the movement of piston from BDC to TDC. At the end of the compression stroke, the fine droplets of fuel oil are sprayed inside the combustion chamber by the fuel injectors and the once the fuel oil attains the self-igniting temperature the combustion takes place.
Expansion Stroke (Power Stroke)-Once the combustion of fuel oil takes place, power stroke takes place. This stroke gives the power to the engine.
Exhaust stroke-This is the final cycle where the CO2, unburnt HC, NOx is eliminated through the tailpipe.
