The typical ways of biomass power generation

Generally, the typical ways of biomass power generation include direct combustion power generation, hybrid combustion power generation and gasification power generation. Direct combustion power generation refers to the transportation of biomass raw materials into boilers to produce steam, drive steam turbines, and drive generators to generate electricity. Hybrid combustion power generation refers to the mixed combustion of biomass and coal.

 

There are two main ways:

1. Feed the biomass raw materials directly into the coal-fired boiler, co-combust with the coal, generate steam, and drive the steam turbine to generate electricity.

2. Firstly, the biomass raw materials are gasified in the gasifier to form combustible gas, and then burned. Coal boilers, combustible gas and coal co-combustion to produce steam, driving steam turbines to generate electricity.

 

Gasification power generation refers to in the gasifier, gasification of biomass raw materials to produce combustible gas. After it is purified, supply to internal combustion engine or a small gas turbine to drive the generator to generate electricity. Biomass gasification power generation in China has over 20 years Research and Development history. It is mainly organized by the Agricultural Science Department for research and delevopment. There are three main problems in the process of experiment and application, for example, low gasification efficiency, low operating rate, and high tar content in gas.

 

Luoyang building material Architecture Design Research Institute has been engaged in the development and application of engineering design and industrial kiln for a long time. It is committed to developing clean, efficient and stable industrial kiln products. Using the guiding thought of engineering application, a rotary biomass gasification retorting furnace has been developed, and the problems of coking and low rate of operation have been tackled. Adopting the modular design concept, the whole equipment has the characteristics of high integration, small occupied area (data) and short installation period, etc. The advanced automatic control system is adopted to realize the functions of one button start and stop, information detection, fault warning and so on. The whole system adopts the distributed energy design scheme, which is very suitable for the layout of towns and farms.

 

LCDRI technical process:

Biomass gasification power generation through the following four steps:

1、 The biomass is made into granules.

2、 Producing combustible gas in rotary biomass gasification retort furnace and purified to become clean gas.

3、Gas enters the internal combustion engine to generate electricity.

4、The waste heat is used to transform the exhaust gas from the internal combustion engine into the required heat energy (steam, hot water) for heating or cooling.

 

Our advantages:

1. High efficiency and continuous gasification technology: The creative high efficiency rotary gasifier has advantages of reliable operation, high gasification efficiency and high gas production quality.

2. Gas decoke purification technology: Reliable catalytic, condensing and washing technologies are used to remove tar from gas, which ensure cleanliness of gas and ensure stable operation of power generation system.

3. One key operation automatic control: The DCS control system is used to transmit temperature and pressure data to the control center to realize the one key operation of the control center and control the whole production process.

4. Strong adaptability: Suit for different types of branches, leaves, straws, animal dung, etc.

5. Modular design -- Container City Installation: The integrated module design is convenient for transportation and layout, compact structure, safe and reliable, stable operation, and strong adaptability of the equipment.

6、Zero emissions, waste heat utilization, flue gas treatment, residue as soil improver.
