据有关资料介绍:全国有砖瓦企业10万多个,占地450万亩,每年烧砖毁田数10万亩,年烧砖耗煤7000多万t标煤;由于粘土实心砖的保温隔热性能差,每年房屋采暖能耗高达1.1亿t标煤,两者合计约占我国全年能源消耗总量的16％以上。这对我国人均耗地只有1.3亩,人年占有能源0.91t标煤而言,形势十分严峻,限制和减少红砖生产与使用更是当务之急。
According to the relevant information, there are more than 100,000 brick and tile enterprises in the country, covering an area of 450 million mu. Each year, the number of burnt bricks destroys 100,000 mu of land, and over 7,000 tons of coal is burned annually. This is due to the insulation of clay solid bricks. The thermal performance is poor, and the annual energy consumption for heating in the house is as high as 110 million tce, which together accounts for about 16% of China’s total energy consumption for the year. This is only 1.3 mu per capita for land consumption in China. For a person with an annual energy of 0.91 tons of standard coal, the situation is very severe. Limiting and reducing the production and use of red bricks is a top priority.
