Embodiment Construction

[0012] The present invention will be further described below in conjunction with drawings and embodiments.

[0013] Such as figure 1 , the type and composition of coal are very complex. The combustion law of coal cannot be described by a mathematical relationship. Therefore, the data related to coal combustion characteristics are generally measured through experimental methods, and the data are processed and analyzed to obtain approximate laws as the basis for evaluating the quality of coal.

[0014] The coal combustion characteristics comprehensive tester is composed of a combustion furnace, a temperature controller, an atmosphere pneumatic controller, a sample feeding mechanism, a thermal balance, a gas measuring instrument and a microcomputer system. Gas measurement adopts Shimadzu CGT-2A CO / CO 2 Portable gas measuring instruments, the rest are self-made.

[0015] The combustion furnace adopts a tubular electric furnace, and simulates the operating temperature through i...

Abstract

The invention relates to a coal combustion characteristic comprehensive tester, which comprises a combustion furnace, a temperature controller, an atmosphere pneumatic control system, a thermobalance,a gas measurement instrument and a microcomputer system. According to the present invention, the ignition temperature, the burn-out time and the proximate analysis value of coal are measured by usinga steady-state measurement method, data processing and analysis is performed by a computer, the basic evaluation is performed on the coal quality, and the scientific basis is provided for the reasonable coal use.

Description

technical field [0001] The invention relates to a coal combustion characteristic comprehensive tester, which is suitable for the mechanical field. Background technique [0002] Coal is an important fossil fuel, and its combustion characteristics are an important index to evaluate its industrial value. Combustion is a complex process in which physical and chemical reactions occur alternately. The content of combustion measurement is very extensive, involving temperature, pressure, flow rate, gas composition (CO, CO 2 , other harmful gases), unburned product components (ash, fixed carbon), etc. There are static (or steady-state) methods and dynamic (or transient) methods for measuring combustion characteristics. It is difficult to complete the comprehensive measurement of combustion characteristics by only one instrument or one method, and the specially designed combustion test bench is too expensive and inconvenient to use. Contents of the invention [0003] The present ...
