Biomass Gasification Power generation

Brief introduction to Biomass Pyrolysis – Gasification Electric Power Generation We hereby recommend the biomass fluid-bed gasification furnace and gas purifying equipment with good performance and cheap price. They can make rice husk, wood chips, coconut fiber dast, saw dust and crop stalks gasified into clean biomass gas fuel. The furnace can reliably work with simply automatic operation. After ignition, 10 minutes later, the biomass gas shall be produced after purifying/cleaning and cooling treatment, which can be supplied to the specially manufactured biomass gas internal combusion engine for electric power generation to meet both for the needs of customers’ own use and selling suplus electric power through connecting into a power grid. However, customers such as factories can be still connected with the national power grid for their power supply is not enough, therefore, the quality and reliability of the engergy are entirely the same as that supplied through the power grid. Major equipment for Biomass Gasification Power Generation Gasification Furnace and cleaning and cooling equipment for Biomass Gas In its early stage, gasification furnace was fixed-bed type, by utilizing the incomplete combustion of biomass fuel in the furnace to produce biomass gas due to lacking of oxygen. In recent years, the application of fluid-bed combustion technology makes the gasification furnace have still higher energy conversion efficiency together with simple, stable and reliable operation of the furnace. Besides, the thermal value of biomass gas has greately been raised, reaching up to 5.0 6.3 MJ/Nm (1,200 1,500 kcal/Nm). The discarded biomass fuel shall be pyrolysised and gasified at high temperature in the furnace and change into biomass gas which can be used after cleaning and cooling treatment as clean gas fuel of internal combustion engine for electric power generation or for supplying urban residents as gas used as household fuel, or for supplying gas to the boilers of rice mills and timber processing mills as well as hot-air furnace – combustion to produce steam or hot-air. The gasification furnace manufactured by using the company’s patent technology has been equipped with a tar cracking apparatus, which is capable of making the gas-phase tar in the biomass gas split to the gas fuel with lower molecular weight, while by providing specially designed dust-removing and tar-removing equipment outside the furnace, by adopting multi-mode methods have been adopted to strictly purify the biomass gas. This furnace is also equipped with perfect operation parameter monitoring instruments of operational, together with centralized control and remote operation to meet the requirements of the internal combustion engine for fuel quality. The gas output of the furnace has been already serialized and can meet the demand of gas supply for 200 2,000 KW electric Power generation. The specifications and parametersare shown in the attached Table 1. If customers have special requirements, unique design, manufacture and delivery can be made on your demand. For the customers who need pretreatment of biomass fuel crushing and drying, we can provide coresponding complete sets of equipment and we also can select and match auxiliary machines, and affiliated apparatus for gasifying and purifying system equipment depending on specific situations, such as water treatment in order to ensure the safe and economical operation. The Internal combustion engine Generator Unit Using Biomass Gas Fuel This Internal combustion Engine is designed and manufactured in accordance with the special requirements for Biomass gas, by adopting the most ideal compressed ratio and the structure of single body mixer outside the generator set and equipped with the reliable explosion –proof apparatus and the electric ignition system without contacts, the hydraulic governing system with excellent performance and the perfect lubricating and cooling systems, thus making this generator set have features of simple structure, solidity and long life, complete protection, stable performance, reliable and easy operation and convenient maintenance. The associated generator is manufactured by using the Siemens Company’s excitation technology without carbon brush, with excellent performance. For the capacity, sufficiet considerations have been given to the tropical wet and hot climate condition to ensure long-term reliable operation. Its performance parameters and technical data are listed in attached Table2, 3.\ Control Panel For generator The control panel associated with the generator unit is equipped with various monitoring and control instruments and measuring instruments as well as reliable automatic air circuit breaker. On the panel, you can directly make remote operation to control the generator voltage, power factor and rotating speed (frequency and the load during parallel operation). The control panel is also equipped with over-current, under-voltage and inverse power relay protection devices to meet the requirements for both single unit or parallel operation). The control panel is also equipped with over-current, under-voltage and inverse power replay protection devices to meet the requirements for both single unit or parrallel operation. If a customer needs multi-unit operation or operation connecting into a power grid, we can supply special synchronous connection panel for safe parallel operation. Auxiliaries and Accessory Equipment In order to realize highly efficient biomass phrolysis gasification to meet the needs of fluidized burning in furnace, for some discarded biomass fuel such as crop straw, pruned fruit tree branch, twig timber, chip from timber processing factory etc, they must be broken up and deciccation-processed. Among the equipments, for which to be used for broken-up, crushing, desiccation, drying, transportation etc. can be supplied as per the customers’ real needs. For those equipment with big dimensions and which are hard to be transported such as fuel tank, gas tank, ash storeroom, high-position sediment pool etc, they can be made on spot according to the drawings provided by the Company or be supplied in a complete in a way of disassembling and assembling by the company.
