摘要： Methods and systems of operating a blockchain mining device using natural gas produced at a hydrocarbon production, storage, or processing site/facility. A generator may be retrofitted to an existing prime mover used to pump the well, and the generator may be used to power the blockchain mining device. Portable mining devices may be hooked up to a casinghead gas supply at a remote, isolated oil facility. Power loading levels may be modulated by adjusting mining transaction levels to correspond with combustible gas production levels.

摘要： A method for operating an internal combustion engine including feeding a pilot quantity of gas fuel, into a prechamber before a piston reaches a top dead center position. The method comprises autoignition of the pilot quantity of gas fuel in the prechamber, feeding a main quantity of gas fuel into the prechamber after the autoignition, and ignition of the main quantity of gas fuel by the conditions in the prechamber that are brought about by the autoignited pilot quantity. The method makes it possible to operate an internal combustion engine purely with methane or some other gaseous fuel, by means of compression autoignition of the pilot quantity.

摘要： An internal combustion engine with controlled ignition comprises a cylinder, a relative piston, and a head between which a combustion chamber is operationally defined. The cylinder and the piston define a first prismatic coupling. The engine also comprises a pre-chamber made directly inside the combustion chamber, and a male element stably connected to an upper surface of the piston to penetrate the pre-chamber at least in one portion of the relative motion of the piston in the cylinder. A spark plug is arranged to look out into the pre-chamber.

摘要： Operating a gaseous fuel engine system includes urging a mixture containing a gaseous hydrogen fuel and air into a pocket in an igniter fluidly connected to a cylinder to form an ignition charge, and igniting the ignition charge via a flame kernel formed by energizing spark electrodes of the igniter. The method further includes igniting a main charge containing the gaseous hydrogen fuel via a flame jet of the ignition charge from the igniter. The pocket is shielded from the cylinder sufficiently to form within the pocket a flow field protecting the flame kernel, while fluidly connected to the cylinder sufficiently to clear the pocket of residual combustion gases.

摘要： A system for supplying compressed gas to several gas-fed devices is based on a liquid piston gas multistage compressor (100). Gas pressure measurements performed at a gas intake (10), an intermediate gas outlet (20) and at an end gas outlet (30) of the system allow controlling respective gas capacities of the compressor stages. Easy and reliable control can thus be obtained for the system operation. Varying the number of the compressor stages allows matching any pressure requirements for the gas delivery to all the gas-fed devices, and varying the gas capacities of the compressor stages allows easy adaptation to variable gas consumptions of the gas-fed devices.

摘要： A gas analysis device is provided that is able to accurately measure a concentration or a quantity of methane contained in a sample gas even if there are variations in the pressure in the sample gas line. This gas analysis device has a sample gas line through which a sample gas flows, a pressure loss mechanism that is provided on the sample gas line, a pressure control mechanism that refers to the pressure on the forward side of the pressure loss mechanism and, by either discharging a portion of the sample gas from the rearward side of the pressure loss mechanism, or by supplying a predetermined gas to the rearward side of the pressure loss mechanism, controls pressure differences in the sample gas line between the front and the rear of the pressure loss mechanism, and an analyzer that analyzes the sample gas flowing through the sample gas line.
