The invention discloses a preparation method of solid alcohol, and obtains the best preparation process of solid alcohol when potassium permanganate is used as a combustion aid and stearic acid is used as a curing agent: the mass ratio of alcohol to stearic acid is 40:1, adding When 4% distilled water is used, the hardness is better compared with other proportions, adding a mass ratio of 0.014% potassium permanganate combustion accelerant can improve the combustion performance of solid alcohol, eliminate black smoke, reduce calorific value loss, and reduce the amount of residue; and On the basis of no additional cost increase, the cooling conditions are changed to improve its combustion performance. Keeping the pH value at about 8 can make the solid alcohol coagulate best. The solid alcohol prepared under the above conditions has the characteristics of high hardness, less residue, high heat release, easy storage, safety and portability, and can be used in catering, tourism, field operations and other industries.

The invention belongs to the technical field of machinery, and relates to a starting method for a generator reversely driving a high-power diesel engine. It involves a starting method in which the generator reversely drives a high-power diesel engine. The generator adopts a combination of a diesel engine and an asynchronous generator. The starting method is as follows: firstly, connect an external high-voltage AC power The voltage of the power supply is converted into the rated voltage of the variable-frequency variable-speed generator set, and provides voltage for the variable-frequency variable-speed generator set; at the same time, the frequency converter activates the control box of the unit and sends out an electric start command for the generator set. Start to rotate and reversely drag the diesel engine to rotate through the disc coupling or high-elastic coupling. When the diesel engine speed reaches the set speed, the generator set control system instructs the injector to inject fuel, and the diesel engine ignites and starts smoothly. The invention reduces the waste of fuel oil and reduces the pollution of discharge.

The invention relates to a vertical environment-friendly boiler for triple dedusting burning wood and biological particle fuel in a boiler, belonging to heating technology. The invention is used for burning wood and biological particles to obtain hot water or steam, and overcomes the defects of black smoke emission, low thermal efficiency, and the like of the similar traditional boilers. The boiler comprises a wind chamber, a fire grate, a carbon powder and gas burning hearth, a first wind inlet, a secondary wind inlet, and a heat exchanger above the hearth. The boiler is characterized in that the hearth is provided with a porous boiler crown of an inclined air vent; the upper end of an inner liner is provided with a smoke blocking wall; a downward screwed smoke tube is arranged between the wall of the inner liner and a lower end socket; an upward screwed smoke tube penetrates through an upper closing plate and a lower closing plate; and a heat exchanger seat of a smoke diversion dedusting chamber in the shape of a ring cavity is arranged on the circumference of the lower end of the heat exchanger. The invention has the advantages of sufficient burning of carbon powders, sufficient gasification and high thermal efficiency. Smoke is dedusted three times in the boiler, and the exhausted smoke has low dust capacity. The invention can be manufactured in a split mode, and is convenient to transport. The tonnage can be greatly increased.
