The invention relates to a small-sized burning furnace for the on-line analysis of a weightless method. The small-sized burning furnace is characterized in that: the small-sized incinerator comprises a furnace body, a furnace hearth, an upper sealing cover, a lower sealing cover and an integrated furnace door, wherein the furnace body is formed by an inner furnace jacket, an external furnace bodyarranged at an outer side of the inner furnace jacket and a heat-insulating filler arranged between the inner furnace jacket and the external furnace body, the furnace hearth is arranged in the innerfurnace jacket of the furnace body, the upper sealing cover is arranged at the top of the furnace body, the lower sealing cover is arranged at the bottom of the furnace body, and the integrated furnace door is formed by fixedly sleeving a heat-dissipating sealing sheet on a power rod, fixedly connecting the upper part of the power rod with the lower part of a crucible bracket, matching a plunger body fixedly sleeved on the crucible bracket with the opening of the inner furnace jacket at the bottom of the furnace hearth in a sealing manner, and matching the heat-dissipating sealing sheet with the opening of the lower sealing cover; a crucible arranged in the furnace hearth is placed on the crucible bracket; and a thermocouple is extended into the furnace hearth and is located above the crucible. The small-sized burning furnace for the on-line analysis of the weightless method has the advantages of small volume, high heat efficiency, little thermal inertia, electric-energy-saving performance, oxidation resistance, long service life and the like and can automatically finish the burning of a combustible substance to be tested.
Description
technical field [0001] The invention relates to a device for on-line detection of combustible content, which is a small burning furnace for on-line analysis of weight loss method. Background technique [0002] The traditional weight loss method for combustible content detection is an off-line laboratory analysis method, and its burning furnace usually uses a muffle furnace, which requires manual operation. Due to its bulkiness, high energy consumption, high-temperature oxidation of heating parts, etc., it cannot be used continuously and for a long time, and its structure is not convenient to cooperate with the actuator to automatically complete the detection process, so it is not suitable for on-line detection occasions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a small incineration furnace for on-line analysis of weight loss method with small volume, high thermal efficiency, energy saving, anti-oxidation, ...
