不同炉型在中南的需求分析数据

为洞察中南地区工业锅炉市场需求，需分析近三年各炉型年度需求数量、蒸发量差异，梳理发展脉络。整体趋势上，传统燃煤锅炉需求年均降 15%，燃气炉年均增 22%、生物质炉增 18%，循环流化床锅炉需求平稳，反映行业向绿色高效转型，为企业研发提供支撑。区域需求分化显著：河南、湖北作为重工业基地，依托煤化工、钢铁产业，循环流化床锅炉年均需求约 300 台（蒸发量 20 - 40t/h），节能改造需求突出，如武钢近三年有 6 台老旧锅炉改造，热效率需超 85%；湖南、广西依托秸秆（湖南年产能超 2000 万吨）、甘蔗渣（广西制糖业年产生超 1000 万吨）等农业废弃物，驱动生物质锅炉需求，长沙企业采购 20 余台秸秆锅炉，南宁糖厂以蔗渣锅炉替代燃煤炉；广东依托珠三角天然气管网，燃气锅炉在电子、食品轻工领域普及，6 - 15t/h 小吨位机型年均需求超 400 台；海南因排放限值严格，加速燃气、生物质锅炉替代传统炉型，海口食品企业换用燃气炉，三亚民宿集群逐步采用生物质锅炉供热。这种区域差异印证行业绿色转型趋势，指引制造企业结合各地资源、产业特点，优化炉型适配性并精准布局。一：数据采集：企业CRM系统中采集近3年工业锅炉不同炉型在中南的需求数量和用热蒸发量数据。
二：算法规则：对采集得到的数据按照如下公式进行计算：
0、说明（当前锅炉型号总蒸发量=蒸发量*锅炉数量）
1、按照年份，省份进行数据透析，得出各个省份三年的总蒸发量
1、对三年的总蒸发量计算平均值x，
2、计算每个数据与平均值的绝对差，
3、计算平均绝对偏差MAD
4：计算相对平均偏差RMD
5、计算相对平均偏差RMD
例如（15,6.5,8）这组数据:（注意：这组数据仅作为举例算法，样例数据中平均值、MAD以及RMD是需要先省份求和再运算）
1.平均值x=9.83;
2.计算每个数据与平均值的绝对差:|15-9.83|=5.17；|6.5-9.83|=3.33；|8-9.83|=1.83；
3.平均绝对偏差MAD=（5.17+3.33+1.83）/3=3.44;
4.相对平均偏差RMD=3.44/9.83*100%=34.99%。
三、数据分析：根据RMD的数值可分析不同炉型在中南的需求量和用热蒸发量。根据计算得出的RMD值对炉型进行分级：亮点系列（RMD≤10%），重点系列（10%<RMD≤35%），普通系列（35%<RMD≤80%），低表现系列（RMD>80%）。

To gain insights into the market demand for industrial boilers in Central and South China, it is necessary to analyze the annual demand volume and evaporation capacity differences of various boiler types over the past three years and sort out the industry development context.

Overall, the demand for traditional coal-fired boilers decreases by an average of 15% annually, while that for gas-fired boilers increases by 22% annually and biomass boilers by 18% annually. The demand for circulating fluidized bed (CFB) boilers remains stable, reflecting the industry’s transition towards green and high-efficiency development and providing support for enterprise R&D.

Regional demand differentiation is significant:
1. Henan and Hubei, as heavy industry bases relying on coal chemical and steel industries, have an annual demand of approximately 300 units of CFB boilers (with evaporation capacity ranging from 20 to 40 t/h), with prominent energy-saving transformation demands. For example, Wuhan Iron and Steel (WISCO) has renovated 6 outdated boilers over the past three years, requiring a thermal efficiency exceeding 85%.
2. Hunan and Guangxi drive the demand for biomass boilers by utilizing agricultural wastes such as straw (Hunan’s annual output exceeds 20 million tons) and bagasse (Guangxi’s sugar industry produces over 10 million tons annually). Enterprises in Changsha have purchased more than 20 straw-fired boilers, and sugar factories in Nanning have replaced coal-fired boilers with bagasse-fired ones.
3. Guangdong, relying on the natural gas pipeline network in the Pearl River Delta, has popularized gas-fired boilers in electronics, food and light industry sectors, with an annual demand of over 400 units of small-tonnage models (6 to 15 t/h).
4. Hainan, with strict emission limits, is accelerating the replacement of traditional boiler types with gas-fired and biomass boilers. Food enterprises in Haikou have switched to gas-fired boilers, and homestay clusters in Sanya have gradually adopted biomass boilers for heating.

This regional difference confirms the industry’s green transformation trend, guiding manufacturing enterprises to optimize boiler type adaptability and make precise layouts based on local resources and industrial characteristics.

### 1. Data Collection
Collect data on the demand volume and heat-use evaporation capacity of different boiler types in Central and South China over the past three years from the enterprise’s CRM system.

### 2. Algorithm Rules
Calculate the collected data according to the following procedures and formulas:
0. Note: Total evaporation capacity of a specific boiler model = Evaporation capacity × Number of boilers
1. Perform data drill-down by year and province to obtain the total evaporation capacity of each province over the three-year period
2. Calculate the average value x of the three-year total evaporation capacity
3. Calculate the absolute difference between each data point and the average value
4. Calculate the Mean Absolute Deviation (MAD)
5. Calculate the Relative Mean Deviation (RMD)

*Note: The example data set (15, 6.5, 8) is for illustration only. The calculation of average value, MAD and RMD should be performed after summing up data by province.
Example calculation:
1. Average value x = 9.83
2. Absolute differences between each data point and the average: |15 - 9.83| = 5.17; |6.5 - 9.83| = 3.33; |8 - 9.83| = 1.83
3. MAD = (5.17 + 3.33 + 1.83) / 3 = 3.44
4. RMD = 3.44 / 9.83 × 100% = 34.99%

### 3. Data Analysis
Analyze the demand volume and heat-use evaporation capacity of different boiler types in Central and South China based on the RMD values. Classify the boiler types into four categories according to the calculated RMD values:
- Highlight Series: RMD ≤ 10%
- Key Series: 10% < RMD ≤ 35%
- General Series: 35% < RMD ≤ 80%
- Low-performance Series: RMD > 80%
