1. But policy of second birth energy burns stimulative rubbish technical application

It is with Zhejiang and Guangdong exemple, at present the online electrovalency of two ground all sets the online electrovalency of garbage power factory under the country.

At present electrovalency (yuan / degree) the country fixes a price (yuan / degree)

2. Build rubbish to burn the plant will be main with big, medium-sized burn the factory is given priority to

The rubbish that our country builds burns plant construction dimensions is more than 600 tons generally / day, our country is big in urban rubbish burns factory processing dimensions often is in be more than 1000 tons / day, burn the factory is in the majority with configuring 2-3 stage incinerator, the dimensions of only station incinerator often is in 300-600 ton / day, suffer the influence of policy, the development of incinerator has large change a trend

3. Furnace discharges furnace and fluid-bed have equal shares, small-sized incinerator market is reduced gradually

Be in our country, big in the city is given priority to with furnace of mechanical furnace platoon. To in small town and inland city and economy developed area, bachelor changes the country of fluid-bed the economic benefits that advantage of technology, price and mix into coal obtain, will still have bigger attraction.

4. The utilization of waste heat that the rubbish inside the near future burns still will be given priority to with generating electricity

Suffer our country but the influence of second birth the sources of energy, and the stability of product sale, favourable electrovalency makes generate electricity become our country rubbish to burn the heat energy of the factory uses means relatively onefold, it is to burn mostly absolutely more than heat is to be used at generating electricity;

In vapour parameter respect, normally rubbish burns parameter of vapour of factory beyond heat boiler is in parameter of lukewarm middling pressure (4MPa and 400 ℃ ) , if raise vapour parameter, will conduce to raise efficiency of utilization of waste heat, raise electricenergy production, increase the income of rubbish factory, at the same time also aggravate of material of more than heat boiler corrode, shortened the service life of equipment, increased depreciation cost. Current, guangzhou plum hole and Zhongshan burn the furnace that the factory uses 3 water chestnut to weigh labour, the attempt uses high pressure of second high temperature 6MPa of parameter of steam of more than heat boiler and 450 ℃ . The economy that uses parameter of high pressure of second high temperature and the adaptability to Chinese national condition still are at present in exploration.

5. The scale that the law does in flue gas processing can increase somewhat

As technical progress and development, dry method craft also is mixed in promotion progress, processing effect has current dry law to rise significantly, the application that is in abroad increases somewhat. Be in Japan, tokyo burns the plant is expensive to environmental requirement, flue gas processing all is used wet processing technology, the capital of a country east in order to be in burn processing of factory flue gas basically uses dry method to handle craft.
