Biomass Power Plant refers to the generation of combustible gases after gasification of biomass, which are purified to drive gas-fired generators to generate electricity. The main body of Biomass Power Project is Biomass Gasifier and generator set. Biomass Power project can be divided into Wood Generator , Rice Husk Power generation and Biomass Generator. Biomass syngas power generation is a pollution-free, low energy consumption, high-benefit power generation project.

PoE Advantages: In addition to providing universal power supply support for connected devices from Ethernet cables, PoE reduces investment expenses, thereby reducing the total deployment cost of integrating into a powered device in a unified IP infrastructure. PoE eliminates the need to install wall power connections for terminal equipment, thereby reducing the cost of power outlets associated with supporting end equipment. It can also install network connectivity equipment in places where local AC power is difficult to deploy, providing greater flexibility.
PoE switches: Ports of PoE switches transmit data signals and can also provide DC power for some IP-based terminals (wireless access point APs, VoIP phones, and IP-based surveillance cameras). Using a standard CAT5 cable, you can provide power to wireless APs and IP cameras. Power over Ethernet (PoE)-optimized power device installation and power management reduces installation time and costs for many new network devices.
PoE: PoE (Power over Ethernet, Power over Ethernet) is a LAN technology that provides DC power to powered devices over twisted-pair cables. It is currently widely used in enterprise and industrial applications.
PSE: Power Sourcing Equipment. The PSE device is a device that provides power for Ethernet client devices. It is also the administrator of the entire PoE Ethernet power supply process.
PD: Power-side device Power Device, PD device is the PSE load that receives power, that is, POE system client devices such as IP phones, network security cameras, APs, and PDAs or mobile phone chargers and many other ether Network equipment (Actually, any device that does not exceed 13W in power can obtain the corresponding power from the RJ45 socket).
IEEE 802.3af: This standard stipulates that the power supply equipment can supply power to power-receiving equipment below 13W through Ethernet. This is sufficient for traditional IP phones and webcams, but with the advent of high-power applications such as dual-band access, video telephony, and PTZ video surveillance systems, the 13 W power supply clearly cannot meet the demand. For this reason, IEEE In 2005, the new PoE standard 802.3at (PoEPlus) was developed to increase the PoE transmittable power.
IEEE 802.3at: IEEE802.3at (25.5W) was born in response to the needs of high-power terminals. Based on 802.3af compatibility, it provides greater power supply requirements and meets new requirements.
Mid-Span: Use the free wire pair that is not used in the Ethernet cable to transmit the DC power. The 4th and 5th feet are connected to the positive pole. The 7th and 8th feet are connected to the negative pole. They are used in ordinary switches and network terminal equipment. Between the network terminals can be powered by network cable, Midspan PSE (midspan power supply equipment) is a dedicated power management equipment, usually placed together with the switch. It has two RJ45 jacks for each port. One is connected to the switch with a short cable and the other is connected with a remote device.
End-Span: It transmits DC power at the same time as the core used to transmit data. Its transmission uses a different frequency than the Ethernet data signal. The corresponding Endpoint PSE (end-powered device) has POE enabled Ethernet switches, routers, hubs, or other network switching devices. It can be foreseen that End-Span will be rapidly promoted. This is due to the use of common line pairs for Ethernet data and power transmission. This eliminates the need to set up dedicated lines for independent power transmission. This is for 8-core cables and matching RJ-standards. 45 sockets are particularly significant.
POE (Power Over Ethernet) refers to some IP-based terminals (such as IP telephones, wireless LAN access points APs, network cameras) without any changes to the existing Ethernet Cat.5 cabling infrastructure. Etc.) While transmitting data signals, it is also possible to provide DC powered technology for such devices. POE technology can ensure the normal operation of existing networks while ensuring the safety of existing structured cabling, and minimize costs.
A complete POE system includes two parts: PSE (Power Sourcing Equipment) and PD (Powered Device). The PSE device is a device that provides power for Ethernet client devices and is also the administrator of the entire PoE Power over Ethernet process. The PD device is a PSE load that receives power, that is, client devices of a POE system, such as IP phones, network security cameras, APs, and PDAs or mobile phone chargers, and many other Ethernet devices (in fact, any power Devices that do not exceed 13W can get corresponding power from the RJ45 socket). Based on the IEEE 802.3af standard, the two establish information links regarding the connection status, device type, and power consumption level of the power-receiving device PD, and use this to provide power to the PD through the Ethernet through the PSE.
The main power supply parameters of the POE standard power supply system are:
1. The voltage is between 44-57V, typically 48V.
2. The maximum allowable current is 550mA and the maximum starting current is 500mA.
3. The typical operating current is 10-350mA and the overload detection current is 350-500mA.
4. Under no-load conditions, the maximum required current is 5mA.
5. Provide three power levels of 3.84 to 12.95W for the PD device, up to a maximum of 13W. (Note that PD classification 0 and classification 4 are not shown and should not be used.) 
Must understand the knowledge of these POEs
Power over Ethernet is the ability to provide 48V DC power on the same Ethernet copper cable. Implementing Power over Ethernet requires two major devices—power supply equipment (PSE), a LAN switch or source power supply on the Ethernet, and a power-up device (PD), a terminal device that receives and uses power to run from an Ethernet cable. .
