For all aspects of biomass energy utilization, it is necessary to do adequate resource investigation work before project decision-making. Since biomass energy is relatively scattered and the collection radius should not be too large, the collection cost of biomass will be greatly improved: Outside the region,
I. The purpose and content of the resource survey All the resources in the field of biomass energy utilization must first be fully investigated before the project decision-making. Since the biomass energy is relatively scattered and the collection radius should not be too large, the biomass will be greatly improved. Collection costs: In addition to a few areas in rural China, the per capita arable land area is only 2 to 4 mu, and each household can only provide 2 to 3 per year. This is a disadvantage to the large-scale utilization of biomass resources. There must be sufficient preparation and countermeasures for the difficulty of collecting resources for project implementation.
The purpose of the resource survey is not only to understand whether there are sufficient resources around the place where the proposed project is implemented, but to analyze the “available amount†within a specific price range based on the survey. The amount of resources that are out of the price is meaningless. Therefore, the situation to be understood by the resource survey should include the flow of straw, local climate impact, straw distribution and transportation conditions, and human environment. The detailed considerations in each case are as follows:
(1) Straw flow direction 1. Returning to the field:
2, feed:
3. Fuel;
4. Industrial raw materials:
5. Collect losses.
(2) Local climate impacts 1. Planting varieties:
2. Multiple cropping index;
3. Frost-free period;
4, rot and mildew may be.
(3) Distribution and transportation conditions 1. Farmland density;
2. Road conditions;
3. The possibility of surface transportation;
4. Water and obstacles to transportation.
(4) Humanistic environment 1. The economic development of rural areas:
2. Farmers' economic income;
3. Farmers' commodity awareness;
4. The awareness of relevant government departments;
5. Local: I: Industry development status:
7. The local environment is tolerant.
II. Resource survey plan The survey plan should be completed before the resource survey work is carried out. The survey plan mainly includes the following contents:
(1) Organizations Clear organizers and consignors, general resource survey work will be combined with specific projects. In the process of implementing the organization, it is necessary to reasonably disregard the organization according to the requirements of the entrusting party.
(2) Participants According to the needs of the investigation, it is necessary to identify the participants of the investigation activities and determine the person in charge of the investigation.
(3) Content of the investigation Clear the contents of the investigation. Such as: basic conditions of county economy; development status of agroforestry; status and mode of treatment of agricultural and forestry production waste; energy use of residents (farmers), utilization of renewable energy (such as solar energy, biogas, etc.); coal resources and coal consumption status Biomass solid forming fuel (produced by wood chip machine) production base demonstration (successful experience and failure lessons); biomass boiler operation; ideas for the development of biomass energy.
(4) Purpose of the investigation Clear the purpose of the investigation. For example, to explore the possibility, methods, methods and existing problems of the development of biomass-scale fuel in the county scale; to explore the possibility, methods, methods and existing problems of biomass energy development; to investigate the industrialization demonstration of biomass solid molding fuel Happening.
(5) Formulating the survey area List the areas of the word survey and clarify the content of each survey point that needs to be investigated.
(6) Survey time and schedule Make a clear time schedule and plan the survey route reasonably.
(7) Determining the survey method According to the identified survey points and survey objects, one or more survey methods are selected. The general survey methods mainly include:
1. Symposium: The “Renewable Energy (Biomass Energy) Development Symposium†will be held, and the leaders of the county government, the departments of development and reform, finance, agriculture, agricultural machinery, environmental protection, relevant townships, and related institutions will be invited to participate, and members of the investigation team. Communicate and discuss together;
2. Field investigation: It is possible to select towns and towns with abundant biomass resources for investigation, and also to investigate the demonstration of biomass pellet fuel:
3. Text collection: collect relevant written materials as needed, such as statistical yearbooks, relevant documents and policies issued by the government;
(8) Relevant preparations Check the relevant materials, make necessary understanding of the basic situation of the area to be investigated, and prepare the investigation outline and questionnaire.
III. County (City) Resource Survey The county (city) resource survey work needs to communicate with the relevant departments of the local government. The Southern Development and Reform Commission proposes 3 to 6 candidate counties to form a long list of candidate counties. For the candidate counties entering the long list, it is necessary to conduct thorough exchanges with the provincial development and reform commissions, energy management departments, environmental departments, and agricultural administrative departments through field investigations, and obtain local yearbooks, socio-economic statistical yearbooks, national economic development plans, and agricultural industries. Written information such as development planning:
On the basis of analyzing various types of data, the basic conditions of each county are summarized. The summary includes at least the following contents: the number of townships. The total population, gross domestic product, cultivated land area and per capita net income, etc., are summarized in the table below. This summary table will serve as the basis for the short list county selection.
area | Alternative county 1 | Alternative county 2 | Alternative county 3 | Alternative county 4 | Alternative county 5 |
Number of townships and towns | |||||
Total population / 10,000 people | |||||
Gross production value / 100 million yuan | |||||
Cultivated land area / 10,000 mu | |||||
Per capita net income |
IV. Township resource survey Select 3 townships with good resource conditions as alternative townships, investigate the straw resources of each township, the potential users of biomass-forming fuels, and the local government's incentive policies for straw utilization. The seminars were conducted in the form of a combination of field visits, and relevant statistical data and policy documents of each township were collected after discussion with relevant departments and personnel of local counties and township governments. The main data on the basic situation of townships in various types of materials can be summarized in the manner of Table 1-2-2.
Alternative county 1 | Alternative county 2 | Alternative county 3 | Alternative county 4 | Alternative county 5 | |
Number of townships and towns | |||||
Total population/person | |||||
Gross production value / 100 million yuan | |||||
Cultivated land area / 10,000 mu | |||||
Per capita net income | |||||

Road/bar | |||||
Total crop straw / 10,000 t | |||||
Straw availability / t | |||||
Average amount of straw per household (t/person) |
The basic data on straw resources in various types of data are summarized in the form of the following table.
While investigating the basic data, it is also necessary to understand the various issues related to the basic conditions for the establishment and operation of the biomass-formed fuel scale project, including: local labor costs, prices of major energy types, and local freight prices. And the use of coal-fired boilers, etc., the summary of such cases can be filled out as follows.

Freight price (yuan/t·km) | ||||
Honeycomb price (yuan/KG) | ||||
