The invention discloses a garbage incinerator which comprises an incinerator body, a grate arranged in the incinerator body, and a blocking piece used for preventing garbage from dropping on the grate, wherein penetrable holes are formed in the blocking piece, and the blocking piece is arranged in the incinerator body, and located above the grate. The garbage fed newly can be laid on the blocking piece due to the arrangement of the blocking piece, so that the garbage can not drop on the grate directly to put out flame on the grate; the garbage can be dried and combusted on the blocking piece, and then drops on the grate for after-combustion through the penetrable holes in the blocking piece; and the combustion is sufficient.

The invention discloses a safe energy-saving barbecue oven, which comprises a support frame, an oven body and a protection device, wherein the upper surface of the support frame is provided with an operation platform; the oven body is arranged on the operation platform; the oven body is in a strip-shaped box-type structure with an opening at the top part formed by a base and two side walls; each side wall is in a double-layer structure with a hollow cavity body formed by an outer plate and an inner plate; a supporting plate used for supporting carbon fire is arranged in the opening; the protection device comprises a water containing tank body; the water containing tank body is arranged at the top part of one end of the oven body; water inlet holes are arranged at the bottom of the water containing tank body; connecting holes communicated with the water inlet holes are respectively arranged in the top surface of the side walls; the connecting holes are communicated with the hollow cavity bodies; and a drainage joint communicated with the hollow cavity body is also arranged in the outer plate of each side wall. The barbecue oven disclosed by the invention is simple in structure, convenient to operate and use, good in barbecue quality, high in efficiency, long in service life of the oven body, strong in practicability and suitable for universal popularization and use, and the safety performance of the oven body can be improved.

The invention discloses an efficient clean coal combustion technology, and belongs to the field of thermoelectricity. According to key points of the technical scheme, the technology comprises the following steps that S1, combustion is conducted, a coal feeding machine is adopted to convey coal powder into a furnace hearth of a circulating fluidized bedboiler; S2, separating is conducted; S3, heatexchanging is conducted; S4, dedusting is conducted; S5, desulphurization and denitrification are conducted, smoke is conveyed to a desulphurization and denitrification tower; S6, coal powder ash is collected, in the S4, liquid containing the coal powder ash is filtered with a filter cloth to obtain coal powder ash mud and filtering water; S7, drying is conducted, the coal powder ash mud is conveyed to a collecting barrel by a spiral conveying machine, and the coal powder ash mud is dried when conveyed; and S8, steam is collected, the steam produced by coal powder ash mud drying in the S7 is conveyed to a back-feeder, so that the steam and coarse particles enter the furnace hearth together. The efficient clean coal combustion technology has the effect of reducing pollution to the atmosphere by fine coal ash.

The invention relates to a method for operating an internal combustion engine. The internal combustion engine includes a cylinder and a piston journalled to reciprocate therein. The cylinder and piston conjointly delimit a combustion chamber into which a spark plug projects. Ignition of the spark plug occurs at an ignition time point controlled by a control unit. The ignition time point is controlled in an idle speed range according to an idle control having a most advanced ignition time point. The engine has a decompression valve which, when open, connects the combustion chamber to a pressure relief space. The valve is open during engine start and closes when pressure in the combustion chamber exceeds a closing pressure. To close the valve, the ignition occurs in the idle speed range for an engine cycle departing from the idle control at a closing ignition time point lying approximately 5 DEG crankshaft angle ahead of the most advanced ignition time point.
