PremixBurner burner is a new type of energy-saving premix burner, which can use higher mixture pressure than ordinary burner, and the flame has better stability. It has been tested to 62.5 mbar with different gas pressures and it maintains a stable flame under all pressure conditions. They can use a wide range of air-fuel ratios and have good regulation performance. Premix burners can burn any standard combustible gas when the mixing pressure is from 2.5 mbar to 150 mbar.
Specially designed refractory pipe "E" and combustion piping ensure the stability of combustion. The long annular orifice “F†reduces the possibility of tempering even at very low mixing pressures. Clogging of the burner can cause gas disturbances. The stepped burner brick "G" guarantees a stable flame at high mixing pressures, short flame lengths, and high heat release conditions. Premix burners are easy to light at a certain pressure. The nozzle "H" is screwed to the burner to ensure a stable and properly positioned flame. The second screw hole is used to determine the correct position of the flame electrode when the restrictor and main flame interface. The complete valve blue component is used in high pressure furnaces. The connection of the nozzle "D" and the support "B" with the valve "C" is for changing the capacity without removing the burner from the furnace. Simplify piping without merging. Each burner has a mixed pressure test port. It is not necessary to remove the burner from the furnace for inspection of the combustion piping.
Introduction of PremixBurner Combustion System Applied to Photovoltaic Glass Passage and Material Channel (One Kiln Four Wire)
1. Two cross-channels and four branch-face channels are much smaller than the main cross-channel area. From our long-term experience and theoretical design for this industry, we recommend the use of a high-speed pre-mixed row-gun combustion system. Cross channel can also be used PREMIXER series burners, depending on your company's specific design program), taking into account the convenience of the system control and site installation and other factors, we have divided the combustion system into two sets of symmetrical The system, that is, the left side of a branch channel plus two work surface channels is a complete system. This system is composed of a main pressure control station, a combustion air blower, and various branch premixed combustion systems. Similarly, the right side consists of a set of The cross-channel and two-face channels are a complete system. The system consists of main pressure-regulating station, combustion-supporting fan, and pre-mixed combustion system of each branch. Because the two systems are completely identical, we introduce the combustion system in one of them: This system is a pathway combustion system, which consists of a mechanical circuit and an electrical control circuit. It can be a self-contained combustion system while leaving an interface. The DCS system is compatible with the entire combustion system.
2, the main working principle of this system:
When the equipment is ready, the combustion fan is turned on, and the combustion air is discharged from the fan and sent to the mixer through each group of valves. At the same time, a negative pressure is formed at the natural gas inlet of the mixer. Open the natural gas inlet valve, and the natural gas is regulated to the working pressure by the pressure regulator valve. If the pressure exceeds the set upper limit, the emptying valve is opened, so that the pipeline can be drained and evacuated. If the system does not have an abnormal alarm, then open the fast shut-off valve, and the gas enters the front of the mixer zero pressure valve through the quick shut-off valve. The negative pressure formed by the air at the inlet of the mixer natural gas is diffracted into the mixer, and the gas and combustion air are mixed in the mixer. The inside is fully mixed, and the mixed gas is sent to the main burner and the combustion starts.
3, the system has air, gas high and low pressure detection, quick cut and explosion-proof devices, air and natural gas flow detection, explosion-proof devices, temperature detection and control functions, if the air, gas pressure abnormal or explosion-proof device action, the system will quickly cut off natural gas, At the same time send the signal to the upper computer.
4. Each channel of the system adopts three-stage display liquid temperature, ie, cooling section, uniform temperature section and discharge section, and controls the combustion temperature in the discharge section. The on-site and control rooms are used to display the temperature of the material section in both directions, which facilitates the work and maintenance of on-site operators and system maintenance personnel. If the DCS system needs to be sent, we will leave the interface.
5, the main function of the discharge temperature control instrument is to achieve on-site air, natural gas flow control and temperature indication. There are two main ways to choose: First, the temperature control instrument independently completes the air and natural gas flow control and temperature indication, that is, the air flow valve receives a continuous voltage or current analog electrical signal output by the temperature instrument to adjust the flow of the combustion air. With the change of the combustion air flow rate, the natural gas flow will follow the combustion air in proportion to change through the mixer, so that the PID adjustment of the system flow is realized; second, the air flow valve sends the DCS system through the analog signal output by the temperature meter and passes the The DCS system judges the temperature of the site and outputs a continuous voltage or current signal to the air flow control valve to adjust the flow of the combustion air. With the change of the combustion air flow rate, the natural gas flow will follow the combustion air in proportion to the change of the combustion air flow through the mixer. , This realizes the system's PID adjustment, and the interface we set aside in the control system.
6. Send the flow signal, temperature signal, pressure signal, etc. to the DCS system to participate in the overall operation of the equipment (we can design our system according to your company's specific requirements to ensure compatibility with the DCS system).
