Abstract

The invention discloses a piston type temperature-constant calorimeter and relates to the field of analytical instruments for calorific values of combustible matters. The calorimeter comprises an inner barrel (1), an oxygen bomb (2), an outer barrel (3), a cover (4) and a case (5), wherein a middle barrel (6) is arranged between the inner barrel (1) and the outer barrel (3), a gap exists between the inner barrel (1) and the middle barrel (6), a positioner (7) is arranged on the case (5), a piston (8) is arranged below the cover (4), both upper and lower surfaces of the piston (8) are arc-shaped convex surfaces, a sealing ring (9) is arranged in a position where the piston (8) and the inner barrel (1) are contacted, an ignition electrode (10) is arranged at the bottom of the piston (8), a temperature measuring probe (11) and an inner barrel stirring mechanism (12) are arranged in the inner barrel (1), and an outer barrel stirring mechanism (13) is arranged in the outer barrel (3). According to the piston type temperature-constant calorimeter, accurate and quick water quantification can be realized during measurement, and the measurement accuracy and the measurement efficiency of the calorimeter are improved.

Description

technical field [0001] The invention relates to the field of analytical instruments for the calorific value of combustible substances, in particular to a piston-type constant temperature calorimeter. Background technique [0002] The calorific value of combustion is one of the most important indicators to evaluate the quality of coal, which is directly related to the price of coal transactions. The instrument used to measure the calorific value of coal is a calorimeter, also known as a calorimeter, calorimeter or oxygen bomb. Calorimeters can be divided into constant temperature type, adiabatic type and double dry type according to the principle. Among them, the constant temperature type has a simple structure and is easy to maintain, and is currently the most widely used. The constant temperature calorimeter is generally composed of an outer cylinder, an inner cylinder, an oxygen bomb, a machine cover, a casing, a stirring system, an ignition device, a control system, etc...
