The invention relates to a biomass gasification fired boiler. The biomass gasification fired boiler can lead biomass fuel to generate combustible gases such as carbon monoxide, dimethylmethane, methane and the like without adding any chemical combustion improvers by adopting the principle of fluidized combustion through heat energy reaction, convert the biomass fuel into excellent combustible gases through preheating and dry distillation; and the biomass fuel is fully mixed with air through the design of primary air, secondary air and a tuyere to completely achieve smokeless, dustless and nuisanceless gas emission. In addition, the design of an underneath type spiral feeding system further improves the integral design of the boiler; and the biomass gasification fired boiler has more scientific feeding, is environment-friendly, and can greatly reduce the labor intensity of workers and improve the working environment.

The invention discloses a cylindrical double-track cam axial piston type crankless internal combustion engine, which relates to the technical field of internal combustion engines and is a multi-cylinder internal combustion engine. The invention provides a novel internal combustion engine; when pistons drive rollers arranged on the bottoms of the pistons for reciprocating movement, the rollers push a double-track cam fixed on a main shaft to rotate, and the power is output from the double-track cam through the main shaft. Outlines of two end surfaces of the double-track cam are in the form that wave crests correspond to wave crests, wave troughs correspond to wave troughs, and the two end surfaces are circumferentially symmetrical. Two groups of cylinders are symmetrically arranged at bothends of the double-track cam, and axis lines of the cylinders have equal distance to an axis line of the main shaft and are parallelly, circularly and evenly distributed. The pistons which have the same axis line and are symmetrically arranged with the spacing of 180 DEG C have the same working state, which ensures that the axial and radial composite force of the double-track cam and the main shaft are zero. A sliding rod at the bottom of each piston slides in a guide groove, which ensures that the side pressure of the piston is zero. Intake and exhaust valves of all the cylinders are intensively controlled by two distributing cams. The internal combustion engine has the characteristics of simple and compact structure, small volume, small impact vibration, steady operation, high power, long service life and so on.

A combustor section (14) is disposed downstream of a nozzle section (11). The combustor section (14) extends from a downstream end of the nozzle section (11) to an entrance of a gas turbine and supplies a combustio n gas which is generated by combusting a premixed gas to a gas turbine. The combustor section (14) is formed by an inner tube and a tail tube unitarily. The combustor (10) is provided with a wall cooling apparatus for cooling a wall surface of the combustor (10). On the inner wall of the combustor section (14), grooves are formed. An entrance for introducing an air for cooling action is disposed on the outer wall of the combustor section (14). The introduced air performs a film cooling and connective cooling in a combined manner. By doing this, the temperature of the combustion gas may be high, and a highly efficient gas turbine is realized.

The invention discloses an energy-saving and environment-friendly domestic garbage incinerator which comprises an incinerator body. The incinerator body is of a hexagonal structure, and the inner walls of the two ends of the incinerator body are inclined inwards. A base is welded to the bottom end of the incinerator body, and a waste discharging port is formed in the bottom of the outer wall of one side of the incinerator body. A feeding port is formed in the outer wall of one side of the incinerator body. Solar cell panels which are distributed at equal intervals are fixed to the top of the outer wall of one side of the incinerator body through bolts. Air inlets which are distributed at equal intervals are formed in the outer wall of one side of the incinerator body. By means of the energy-saving and environment-friendly garbage incinerator, airflow outside the device is converged to form air through arc plates, air force passes through the inclined air inlets to form wind volumes under the help of screw blades, the effective combustion area and the oxygen content of garbage are increased, dust particles in waste gas are ionized after electric conduction of a big-end-up conical metal sleeve is conducted, the dust particles fall layer by layer after dropping, and the environment-friendly capability of the device is improved again.

The invention discloses an outer convex inner arbitrary gear difference cam rolling moving transmission internal-combustion engine, relating to the field of fuel gas power and belonging to a multi-cylinder internal-combustion engine. The invention provides a novel internal-combustion engine; eight cylinders are distributed on the periphery of an outer convex inner multiphase inner cam symmetrically in a ring shape, so that a resultant force of the outer convex inner multiphase inner cam is zero; each cylinder piston directly acts on the outer convex inner multiphase inner cam through a push rod; and power is transmitted to an output shaft connected with a central wheel key by the outer convex inner multiphase inner cam through arbitrary gear difference inner cam rolling moving movable gear transmission. With the adoption of the internal-combustion engine, a connecting rod and a crank shaft in the traditional internal-combustion engine are saved; an outer convex multiphase inner cam rolling moving transmission mechanism has the characteristics of having no eccentric mass, and having an inertia force and working load self-balancing; the rotating speed of the output shaft depends on transmission ratio of movable gear transmission; when a movable gear frame is fixed, output by a central wheel is in low speed and large torque; and the internal-combustion engine can be widely applied to the fields of high-power engineering machinery and military and the like, such as excavators and armored cars. The internal-combustion engine is simple and compact in structure, small in axial size, self-balancing in stress, and stable in rotating.

A swash plate type opposed-piston two-stroke external-combustion engine, comprising a cylinder block, a main shaft hole is opened in the middle of the cylinder block, six axially penetrating cylinders are evenly arranged on the outer periphery of the main shaft hole, and two front and rear cylinders are arranged opposite to each other in the cylinder. There are two pistons, and the front and rear ends of the cylinder are equipped with compressed air rotary valves, and the middle of the cylinder is equipped with a working rotary air valve. Among the twelve pistons, nine pistons take in air from the environment through the compressed air rotary valves and perform one-stage compression. To the gas storage branch pipe, the three pistons take in air from the gas storage branch pipe through the compressed air rotary valve and perform secondary compression to the combustion chamber. Among the six cylinders, three cylinders perform primary work, and three cylinders perform secondary work. The first-stage work cylinder is the cylinder where the piston of the second-stage compression is located, and the second-stage work cylinder is the cylinder where the two pistons before and after the first-stage compression are all performed. This design improves the utilization rate of heat energy.
