Turnkey solutions for HFO power generation plant

Stationary Power Station -Off grid/ On grid solution

Rockwill Strogly tie with Eminvac and China Brand Generator company to provide with Whole solution for Stationary power station, Power factory.
Since 1999, to now. We with our partner C.S.I  has ever built more than 200 power plants with power capacity from 1MW to 42MW all over the world. with unit power range from 200kW to 3500 kW.
Most of the power plants are 24 hours continuously operating ones. The fuel used varies from diesel, heavy fuel oil, petroleum, bio-fuels, dual fuels and etc. The power plants were widely used in various industries such as cement, textile, mining, wharf, steel and so on. It can also be used in towns and cities as main power supply or emergency backup power supply at the peak power demand time.
Engineering Technology: In response to customer’s particular power load characteristics, an appropriate technical configuration (speed control system, excitation system, distribution system, etc.) will be adopted. We are able to provide complete solution from scheme design to technical support.
Engineering Organization: The construction engineering drawings design work will be carried out based on the actual environments and conditions at the particular project site and our previous power plant construction experience, which effectively prevent civil construction risks and organize the engineering team to carry out the project installation, commissioning, operation and etc.
Technical training: On-site technical training and maintenance technical training will help the owners to possess the plant maintenance capabilities. Or, customers can organize their technical engineers to our company for equipment technical training.
Service: We’ve established regional service organizations through the service network map, and maintained long-term strategic cooperative relationship.

What is HFO

HFO is HEAVEY Fuel oil (also known as heavy oil, marine fuel or furnace oil)  which is a fraction obtained from petroleum distillation, either as a distillate or a residue. In general terms, fuel oil is any liquid fuel that is burned in a furnace or boiler for the generation of heat or used in an engine for the generation of power, except oils having a flash point of approximately 42 °C (108 °F) and oils burned in cotton or wool-wick burners. Fuel oil is made of long hydrocarbon chains, particularly alkanes, cycloalkanes and aromatics. The term fuel oil is also used in a stricter sense to refer only to the heaviest commercial fuel that can be obtained from crude oil, i.e., heavier than gasoline and naphtha.

Heavy fuel oils continue to be used in the boiler "lighting up" facility in many coal-fired power plants. This use is approximately analogous to using kindling to start a fire. Without performing this act it is difficult to begin the large-scale combustion process.

The chief drawback to residual fuel oil is its high initial viscosity, particularly in the case of No. 6 oil, which requires a correctly engineered system for storage, pumping, and burning. Though it is still usually lighter than water (with a specific gravity usually ranging from 0.95 to 1.03) it is much heavier and more viscous than No. 2 oil, kerosene, or gasoline. No. 6 oil must, in fact, be stored at around 38 °C (100 °F) heated to 65–120 °C (149–248 °F) before it can be easily pumped, and in cooler temperatures it can congeal into a tarry semisolid. The flash point of most blends of No. 6 oil is, incidentally, about 65 °C (149 °F). Attempting to pump high-viscosity oil at low temperatures was a frequent cause of damage to fuel lines, furnaces, and related equipment which were often designed for lighter fuels.

For comparison, BS 2869 Class G heavy fuel oil behaves in similar fashion, requiring storage at 40 °C (104 °F), pumping at around 50 °C (122 °F) and finalising for burning at around 90–120 °C (194–248 °F).

Most of the facilities which historically burned No. 6 or other residual oils were industrial plants and similar facilities constructed in the early or mid 20th century, or which had switched from coal to oil fuel during the same time period. In either case, residual oil was seen as a good prospect because it was cheap and readily available. Most of these facilities have subsequently been closed and demolished, or have replaced their fuel supplies with a simpler one such as gas or No. 2 oil. The high sulfur content of No. 6 oil—up to 3% by weight in some extreme cases—had a corrosive effect on many heating systems (which were usually designed without adequate corrosion protection in mind), shortening their lifespans and increasing the polluting effects. This was particularly the case in furnaces that were regularly shut down and allowed to go cold, since the internal condensation produced sulfuric acid.

Environmental cleanups at such facilities are frequently complicated by the use of asbestos insulation on the fuel feed lines. No. 6 oil is very persistent, and does not degrade rapidly. Its viscosity and stickiness also make remediation of underground contamination very difficult, since these properties reduce the effectiveness of methods such as air stripping.

When released into water, such as a river or ocean, residual oil tends to break up into patches or tarballs—mixtures of oil and particulate matter such as silt and floating organic matter- rather than form a single slick. An average of about 5-10% of the material will evaporate within hours of the release, primarily the lighter hydrocarbon fractions. The remainder will then often sink to the bottom of the water column.
