�?Sweetener
�?Radiated coolant system
�?Fuel depot
�?Pump station
�?Maintenance workshop and warehouse
52MW power station contains power station, exhaust system and exhaust boiler, radiated coolant system，fuel depot, pump station, maintenance workshop & warehouse and working building. Generating sets, auxiliary machines, supply unit, lube filtration separator and control system are all installed in power station. If you don't consider terrain factors influence, the ideal power station can take up an area of 200m×165m. While the actual station design could be adjusted by weather, environment and terrain, but principle of proximity should be considered to prevent too much a long pipe arrangement. At the same time, the heat of heavy fuel oil tank is realized through the vapor of exhaust boiler, so the short line is in favor of heat insulation.
There is the general layout of 52MW power station in the annex
The heavy fuel oil could be the main fuel and light diesel oil the auxiliary fuel. With the main
generating sets parallel operation, each unit can input or exit operation. The control system could adjust power balance, power of different sets, which has protective measures of inverse power, over current, etc.
(Suggestions) The power station need to collocate a 1000kVA auxiliary engine, which can supply the black start power, light fuel oil, 24V storage battery start, power -0.40kV, frequency-50Hz, PF-0.8pf, and rotated speed-1500rpm. When the power station comes into good running, the auxiliary engine turns to the emergency standby sets.
Transformer, collocate by power station, provide the main auxiliary equipment with working power supply, the electricity of station lighting and domestic consumption.
5.2 Characteristics of HFO power station
(1) Highly-structured corollary equipment, flexible installation site and short construction period
The corollary equipment of heavy fuel oil generating sets is rather simple for little corollary equipment, small volume and light in weight. Compared with water turbine-generator set needed to dam, vapor generating set needed to boiler, fuel storage, and water treatment system, the diesel generating set has advantages of small occupation, high construction speed and low invest cost.
Modularity unit system used for heavy fuel oil generating sets, flexible arrangement according to the terrain, which is fit for construction of mountain area and mine area, subjected to small regional terrain restrictions.
(2) High thermal efficiency, low fuel oil consumption and low operation cost
The heavy fuel oil machine extended from diesel is the highest thermal motors of thermal efficiency, of which the effective thermal efficiency is 40%-50%, the high-pressure steam turbine is about 20%- 40%, and combustion gas turbine is about 20%-30%. So fuel consumption is rather low about 178g/kWh. The power station form applied with heat and power cogeneration, has the higher whole energy conversion efficiency, and the thermal power gets more fully used.
(3) The rapid starting and can quickly reach full power
The heavy fuel oil generating sets may use heavy fuel oil and light fuel, which could reach full loaded operation in 3 min of emergent condition (light fuel oil used on emergency ), and in 10 min of normal operation condition (starting uses light fuel oil, and heat engine uses heavy fuel oil ),while the thermal & electricity steam power equipment generally needs 3-4h from starting to full load. What’s more, the shutdown process of diesel is rather short, started and shutdown frequently.
(4) Simple maintenance, small conventional maintenance work, little operation staff, overhaul period of 36000h (related to the fuel oil quality), and low operation expense.
(5) Convenient unit combination and upgrade, capacity easy to extended
Each capacity of MAN heavy fuel oil power station generating sets, ranging from 3000kw to 21000kw, which has the advantage of fitting for more power supply load with more selected capacity. When adopting heavy fuel oil power station generating sets as power, the installed capacity may dispose neatly according to actual need, which can increase power set capacity in the after enlargement & production. The expansion of access is simple and smart, so the expense of primary construction investment is much lower.
