Exhaust system.
Combustion chamber:
width is 300±30mm is 1000±100mm. A thermal with a heat transfer insulation material coefficient of and the length
about 0.7 W.m-2.K-1 is used on requirements both sides of the test the rear wall and chamber. Meet  of 5.1 of GB/T
Air supply system: 4.2 requirements to meet the of Section GB/T31248-2014.
Air inlet size at the bottom of the test chamber: (800 ± 20) × (400 ± 10) (mm). An airbox is installed at the air inlet,
and the air directly chambers airbox installed introduced through an under the into the combustion air inlet and the
The size of the air box is the same as the airbox is of the air inlet. The 150mm±10mm The air size depth of the is blown

Into the air box by a fan through a rectangular straight pipe The rectangular pipe is 300mm±10mm wide, 80mm±5mm

High and 800mm long the distance between the bottom surface and the bottom surface of the air box is 5~10mm.

The pipe is parallel to the bottom surface and is laid along the centerline of the burner and introduces air through the

Middle of the longest side of the air box A grille is installed at the air inlet to make the air flow uniform and consistent.

The grille is made of 2 mm thick steel plate with a hole having a nominal diameter of 5 mm and a center distance of 8

Steel ladder type:
Common steel ladder: wide (500 ± 5), high (3500 ± 10) mm; material test requirements installation method is. The complies with the USU304 stainless steel of 6.5.1 GB/T18380 and.31-2008 of GB/T31248

Smoking hood:
The hood is installed directly above the bottom surface combustion chamber, 200mm~400mm above the exhaust vent of the combustion exhaust vent of the chamber. The to the longest side of the venting port, and the minimum longest side is the parallel size of the is 1500mm x 10

The exhaust to the smoking hood The inner pipe is distributed at the connected measurement diameter of 300 mm. In order to form D of the pipe is a uniform flow point, the straight length of the pipe

Installation position: The two-way volume probe measures flow in the exhaust pipe. The probe is installed at the centerline of the pipe with a beginning of the exhaust pipe, and the length of the connecting pipe to the end of the length of 2400mm from the exhaust pipe is 1200mm. The length of 32 mm and the probe is a cylinder with an outer
diameter of 16 mm and is made of stainless steel. The gas chamber is divided into two identical chambers, and the
pressure difference between the two chambers is measured by a pressure sensor. Meet the requirements of 4.5.1 of

Sampling probe: 

The sampling probe is installed in the probe is a cylinder cylindrical probe is interference with the to reduce with the probe is a cylinder with the flue gas is well mixed. The sampling surrounding flue gas flow The sampling position of the flue gas is Set along the entire diameter of the exhaust pipe. To prevent the soot from clogging the sampling probe, the direction Of the small hole on the sampling, the probe is adjusted downward. The sampling probe is connected to oxygen and Carbon dioxide gas analyzer through a suitable sampling tube Meet the requirements of Section  of GB/T

 Sampling system:

Sampling system consisting of: sampling tube, soot filter, cold trap, drying column, pump, and waste liquid

Regulators can ensure the effective collection of flue gas samples and absorption of exhaust gas.

Install a smoke exhaust fan at the end of the exhaust pipe. The air discharge capacity of the fan is greater than
1.5m3/s at a temperature of 25 °C and normal pressure. The fan power is 7.5kw.

Frequently Asked Questions:-    

What is the difference between BS and EN standards?

A BS standard is British or UK used for UK engineering equipment designs. Other countries may stipulate their choice. EN standard is the use UK standards but by European regulatory standard, again used for the design and servicing of equipment by the European Union countries regulatory code engineering

What does a fiber optic cable do?

A fiber optic cable contains strands of glass fibers is a network cable inside an insulated casing. They’re designed for long-distance, networking, and telecommunications. Compared to wired cables, higher bandwidth high-performance data and transmit data over longer fiber optic cables provide distances.
