Abstract: A protection structure of a sampling tube of a tank truck is provided. A positioning and protecting base is provided around an outer circumference of the sampling tube. The sampling tube includes a sampling output port for connection with a sampling output hose. The positioning and protecting base includes a through hole. The sampling output port extends through the through hole to partly project outside of the positioning and protecting base. With such an arrangement, the stiffness and strength of the entire sampling output port are enhanced for resisting impact and hit, and readiness of connection between the sampling output port and a sampling output hose is not negatively affected to thereby improve usage performance of the sampling tube.

Abstract: The present invention discloses a method for increasing combustion efficiency, which comprises steps of: providing a combustible material with the components thereof having an identical ignition point, and placing the combustible material in a combustion space; measuring an ambient temperature of the combustion space, and predetermining a first temperature higher than the ambient temperature; heating the combustible material to the first temperature in a non-combustion way; supplying to the combustion space a combustion-supporting gas having a second temperature higher than the first temperature, and the combustion-supporting gas is air; and igniting the combustible material to be burned in the combustion space.

Abstract: A method for improving combustion efficiency as combusting a pure substance is disclosed. The method is started from deciding an environmental temperature of a combustion environment, setting a first temperature higher than the environmental temperature, and uniformly heating the pure substance to the first temperature so as to shorten the temperature drop between the outer surface and the inner portion of the pure substance as far as possible. Simultaneously, after a combustion-supporting gas is provided and heated to a second temperature and the combustion-supporting gas is supplied to the combustion environment, the pure substance is ignited. The steps described above can accelerate the temperature raising as combusting the pure substance, so as to be more close to complete combustion, thereby improving efficiency and reducing contaminant production.
