摘要:
A liquid fuel obtained by blending heavy oil by selectively introducing hydrocarbon substances. The liquid fuel consists of a light oil component consisting of C6-C12 alkane, a catalytic component consisting of C13-C16 alkane, and a heavy oil component. On the basis of the liquid fuel, the mass fraction of the heavy oil component is 10%-90%, the mass fraction of the light oil component is 0-49%, and the mass of the catalytic component accounts for 86% or more of the mass of the light oil component; and the liquid fuel may also contain an aromatic hydrocarbon having a mass fraction of 0-15%. The obtained liquid fuel has good driving performance, combustion performance and safety, and can be applied to a diesel engine system, a diesel/heavy oil combustion system, etc., as a mixed fuel oil.

Herein disclosed is a voltage isolation circuit coupled to power supplies. The voltage isolation circuit comprises a series switch group controlled by a first control signal, a parallel switch group controlled by a second control signal, and a first high impedance element. The series switch group comprises a transistor arranged in a first current loop and having two channels connected to one of the power supplies respectively. The first high impedance element, coupled to the transistor in parallel, has a measurement terminal and two ends, connected to one of the power supplies respectively. When the series switch group is conducted, the power supplies are coupled in series in the first current loop. When the parallel switch group is conducted, the power supplies are coupled in parallel in a second current loop. Impedance values measured from the measurement terminal to each end of the first high impedance element are identical.

A method for compression of an incoming feed air stream using at least two variable speed compressor drive assemblies controlled in tandem is provided. The first variable speed drive assembly drives at least one compression stage in the lower pressure compressor unit driven while the second variable speed drive assembly drives higher pressure compression stage disposed either in the common air compression train or the split functional compression train of the air separation plant. The first and second variable speed drive assemblies are preferably high speed, variable speed electric motor assemblies each having a motor body, a motor housing, and a motor shaft with one or more impellers directly and rigidly coupled to the motor shaft via a sacrificial rigid shaft coupling.

A lamp power assembling structure and method, the lamp power assembling structure is installed indoors and is connected an indoor power source, and includes a lamp power seat and a lamp fixing seat. The lamp power seat has a first power connector for connecting to the indoor power source and two sliding trenches. Each sliding trench has an arced channel and an enlarged hole formed at an end of the arced channel. The lamp fixing seat has a second power connector corresponding to the first power connector and two fasteners separately corresponding to the two enlarged holes. The two fasteners are separately inserted into the two enlarged holes, and the lamp fixing seat is rotated about the first and second power connectors so as to make the two fasteners separately to be engaged with the arced channels to fix the lamp fixing seat to the lamp power seat.
摘要:
In a burner in which fuel and gaseous oxidant are fed into the burner and combusted to produce a flame that extends out of an end of the burner, the noise produced by the burner is lessened by incorporating into the burner a baffle composed of a metal plate having a certain distribution of holes through the plate and a layer of metal filaments, and optionally a second metal plate.

A temperature and humidity sensing device including a body and a temperature and humidity sensor is provided. The body has an inlet hole, an outlet hole, and a flow channel. The inlet hole and the outlet hole are opposite to each other, and the flow channel is configured to communicate the inlet hole and the outlet hole. The temperature and humidity sensor is disposed in the flow channel. The temperature and humidity sensor is configured to sense the relative humidity of air in the surrounding environment of the body during the air in the surrounding environment of the body flows into the flow channel from the inlet hole and flows through the flow channel to flow out from the outlet hole.
