Provided is a method for predicting and evaluating adhesion of combustion ash in a coal-mixed combustion boiler in which biomass is used as renewable energy, the method comprising: ashing a sample to prepare an ashed test sample, the sample being obtained by mixing the biomass with coal that is main fuel of the coal-mixed combustion boiler, at a predetermined additive ratio; sintering the ashed test sample under a combustion temperature condition of the coal-mixed combustion boiler to generate sintered ash; testing the sintered ash by a rattler tester to obtain a sticking degree from a ratio obtained by dividing a weight of the sintered ash after the test by a weight of the sintered ash before the test; and evaluating in advance an adhesion state of the combustion ash in the coal-mixed combustion boiler on a basis of the sticking degree.

Provided is an abrasion test apparatus for measuring an abrasion state of a workpiece, including: a workpiece holding mechanism holding the workpiece; a contact tool repeatedly making contact and non-contact with the workpiece; a rotating mechanism holding the contact tool to be freely rotatable; and a heating mechanism intermittently heating an end portion of the contact tool.

An automatic test system and method for mechanical parameters of surrounding rock applicable to a TBM. The system includes: an aggregate portion collecting a rock slag in a TBM tunneling process in real time; a gripping portion gripping any rock slag from obtained rock slags; a visual processing apparatus performing three-dimensional imaging for a rock slag under test in an infrared ranging manner; calculating positions of loading points for an abrasiveness test experiment, and determining, based on a spacing between loading points, whether rock slag under test meets a requirement; and determining actual positions of loading points if the rock slag under test meets the requirement, and determining a region, on a surface of rock slag, that meets a set condition as an action region for abrasiveness test experiment; and a rock abrasiveness test apparatus automatically performing an abrasiveness test for a rock slag under test that meets a requirement.

A portable environmental testing system for environmental testing with particulate matter, such as sand and dust, is disclosed. The components of the system are largely contained within a modular container, such as an intermodal shipping container. The testing system uses a feeder to feed precise amounts of particulate matter into an injector, which injects the particulate matter into an airflow that leads to a nozzle assembly. The airflow itself is generated by a compressed air system. The material input station, for inputting particulate matter, includes operator protection features, like a negative draw fan. The system may be provided with wheels and a tow bar.
