Product Description

ISO834 EN1363 Fire Testing Horizontal Furnace

Product Details

Introduction

According to the requirements of fire protection, the fire resistance limit test should be carried out for all kinds of beam and plate load-bearing members. According to the requirements of standard EN1363-1,1363-2,hydrocarbon curve and relevant requirements of ISO834, the fire resistance test should be heated by open flame, so that the specimens are subjected to similar flame effects as the actual fire. This test furnace simulates the actual heating process of the fire, and meets the requirements of the fire resistance limit test of the specimen, and comprehensively evaluates the fire resistance of the component.
 

 

Furnace structure


The design life of the furnace is more than 20 years. The construction of the furnace adopts GOVMARK technology of the United States. Five-layer structure, when the inner layer is 1300°C, the outer temperature is normal temperature; Long service life, the inner layer of thermal insulation materials (wear parts) easy to replace. Five layers of structure, from the outside to the inside respectively: the first layer for the steel structure frame; The second layer is built with red bricks; The third layer for refractory high temperature asbestos; The fourth layer is firebrick; The fifth layer contains zirconium refractory high temperature cotton, refractory temperature reaches 1600ºC.

Scope of Application
It is suitable for determining the fire resistance characteristics of all kinds of steel structure fire retardant coatings used in indoor and outdoor buildings under standard fire conditions
 

Product Features

1. A furnace can be multi-purpose, can be compatible with multiple standards;
2. Using high precision acquisition card, collect the temperature, pressure, flow and other aspects of the data, microcomputer analysis, processing and control, the real information of combustion is generated in real time, and the results are obtained directly by microcomputer analysis and judgment. The whole machine adopts high quality components to ensure the system high quality, high speed operation, with advanced nature.
3. Adopt high precision acquisition card + multi-channel module +PLC+ computer, implement PID automatic control mode, stability, repeatability, reproducibility.
4. Using WINDOWS XP operating interface, global precision equipment special development software Lab-view, interface style is fresh, beautiful, simple. During the test, the measurement results can be displayed in real time and the perfect curve can be dynamically drawn. The data can be permanently saved, accessed and printed out, and the report can be printed directly. With high intelligence, guided menu operation, simple and intuitive characteristics, make the test results more accurate.
5. Furnace design life of more than 20 years, furnace construction using GOVMARK technology. Five-layer structure, inner temperature 1600ºC, outer temperature is normal temperature; Long service life, the inner layer of thermal insulation materials (wear parts) easy to replace.
6. It has multiple safety protection systems including air duct thermal protection, pressure release protection, leakage protection, gas leakage detection, gas pipeline safety protection, burner safety protection, and other safety facilities to improve the safety factor in an all-round way.
7. The high temperature hot air extracted from the furnace is cooled by water and air, and the water is recycled by circulating water, which improves the energy-saving effect.

2. Gas Main control system: See Figure 2
Composition: including control system, air supply system, combustion system, protection system and feedback system

3.  Gas pipeline (Physical picture)

It is composed of manual butterfly valve, filter, gas gas-liquid separator, secondary pressure reducing valve, gas overpressure release valve, high pressure switch, low pressure switch, solenoid valve (cut-off valve), pressure regulating valve, gas pressure gauge, seamless steel pipe and gas leakage alarm. It can realize filtration, voltage regulation, flow metering, high and low pressure and other fault state automatically cut off functions to ensure safe combustion. Set gas alarm if there is a leak automatic alarm, at the same time gas solenoid valve automatically cut off and stop gas supply

4. Air Pipes
4.1 Composition
It is composed of fan, frequency converter, manual butterfly valve, low pressure switch, air, gas and liquid separator, etc.
4.2 The air supply adopts two air supply channels, and the fan power is 7.5kw. The fan adopts centralized control and interlocking control with the burner to realize fault alarm and automatically cut off the gas supply; See Figure 4-2
                 

                        4-1. Air supply system                                                                                              4-2. Air is supplied in two ways
5.Burners: A total of 16 high-speed gas burners of 320kw; See Figure 5
6. Gas:See Figure 6
6.1 Used to fill liquefied petroleum gas (LPG or pipeline natural gas (LNG);
6.2 Using bottled liquefied petroleum gas as fuel requires gasifier gasification to convert liquefied petroleum gas from liquid phase to gas phase. Multi-bottle pipeline installation, that is, 8 bottles in series as a group, two groups of 16 bottles, automatic control circuit, test when the pressure is lower than the set value, liquid phase switching valve will automatically switch to another group, so as to prevent the test gas suddenly exhausted, so that the test is interrupted.
6.3 Fuel consumption: (300m~550) m3/h.
