Abstract

A controllable compound calefactive structure column heating furnace used for fire test of architecture structure is provided, which comprises furnace body whose lumen is hearth, lower furnace mouth and upper furnace mouth are set on the bottom and top of the furnace body respectively, heater coil is placed on the wall of hearth, at least four smoke vents on the top of the furnace body are distributed around the upper furnace mouth, at least four gas-jets are set around the hearth on the bottom of the furnace body assembled by two or three segments. The controllable compound calefactive method has advantages of electric cooker temperature rising and gas temperature rising and avoid the disadvantages thereof, improves the speed of temperature rising and makes the temperature rising control near to international standard calefactive curve, and near to real fire more, reduces test cost and circumstance pollution greatly.

Description

technical field [0001] The invention relates to a heating furnace capable of compound temperature rise, which is mainly used for building structure fire tests, and can controllably heat up and down according to test or process requirements. Background technique [0002] At present, there are two types of heating methods for building structure fire tests: electric furnace heating and gas or fuel oil heating. Electric furnace heating has the characteristics of safety and reliability, high measurement and control accuracy, easy operation, stable temperature control and no pollution, and less investment. According to the requirements of different test purposes, it usually only needs 30,000 to 100,000 yuan; but the heating speed of electric furnace is slow and difficult. It meets the standard heating curve of fire resistance test and the test requirements of using open flame as stipulated in "Fire Resistance Test Method of Building Components GB / T 9978-1999". The heating method ...
