Problems solved by technology

However, the cost is too high. In addition to the need for imported aerosol generators, it is also necessary to use imported paraffin oil. Therefore, domestic fire detector manufacturers generally find it difficult to accept
In addition, paraffin vapor, as the smoke source for testing, can only be used to detect the response threshold of point-type smoke detectors, and cannot test the detector's response sensitivity to real smoke.

Abstract

The invention discloses a smoke combustion furnace, which belongs to the technical field of performance testing of a fire detector and particularly relates to the smoke combustion furnace for producing a test smoke source so as to test a smoke fire detector. The smoke combustion furnace has the characteristics of safety, high efficiency, energy conservation, sensitivity in temperature control and the like. The following technical scheme is adopted: the smoke combustion furnace comprises a furnace body, wherein a smoke tube is arranged above the furnace body and is communicated with the furnace body; the lower part of the smoke tube is provided with an axial flow fan; the furnace wall of the furnace body is provided with a furnace door; the furnace door is provided with an observation window; an electric heating plate is arranged at the bottom in the furnace body; and air inlets are formed in the periphery of the electric heating plate at the bottom of furnace body.

Description

technical field [0001] The invention belongs to the technical field of fire detector performance testing, and in particular relates to an ash-smoke combustion furnace, which is used to generate a test smoke source so as to test smoke-sensing fire detectors. Background technique [0002] Building fire prevention is an important aspect of fire protection work. In the field of building fire prevention and control, point-type smoke detectors are currently the most widely used fire detection products. It realizes early detection and alarm by monitoring the concentration of smoke in the air in the protected area. Through a series of alarms and linkage actions, it notifies personnel to evacuate, realizes early prevention and control of fire, and reduces personnel and property losses. [0003] During the development and production process of point-type smoke detectors, the ability of the detector to respond to smoke must be tested. According to the technical requirements of GB4715-2...
