Garbage burning power generation is an important new energy household related to people's livelihood. From the perspective of household policy, China has basically clarified the development direction of garbage disposal and environmental trend. Since 2016, the state has formulated a series of generous policies and measures for sustainable and healthy development of garbage burning power generation. The national energy administration, the former Ministry of environmental protection, the Ministry of housing and urban construction have also issued relevant documents to support the development of garbage burning power generation.
However, as the preliminary work of waste combustion power generation, the relevant methods of waste classification and recycling are not clear and implemented, and there is no sufficient restraint and incentive mechanism to make waste classification universal, which can not create good conditions for waste harmless disposal and waste disposal. Meanwhile, corresponding policies such as decision-making, manufacturing control, investment, tax, subsidy of standard containers still need to be improved One step to improve, especially the subsidy policy for waste disposal, to explore the instability in the vicious competition, and to formulate the corresponding preferential policies are the joint of waste combustion power generation in developed countries. Without preferential policies and various subsidies, it is difficult to realize the household ownership of garbage burning power generation. Therefore, it is necessary to improve the relevant legal policies, relevant policies, control and economic policies of garbage burning power generation industry.
At present, coal, kerosene, natural gas and other traditional fossil fuels have brought many problems to human beings, such as environmental pollution, greenhouse effect and so on.
There are many petrochemical and chlor alkali enterprises in China. Many petrochemical and methanol hydrogen production enterprises produce a large number of domestic tail gas with hydrogen content of 50% - 60% or even more than 90%, which is called hydrogen rich tail gas.
Hydrogen rich tail gas has the characteristics of flammability, explosion, large volume, transportation difficulty, etc., and contains certain harmful organic substances, which can simply discharge environmental pollution; the disposal and utilization of hydrogen rich tail gas is not only conducive to environmental protection, but also may be about energy saving and consumption reduction, so as to advance the economic benefits of enterprises.
For large-scale water tube boilers, the assimilation of FGR recirculated flue gas and fresh air generally provides assimilation bellows. Different positions are divided into pre mixing and pre mixing. Pre mixing is to arrange assimilation bellows in front of the blower to assimilate the recycled flue gas and fresh air. When the fan is sent into the air, it is sent to the burner to participate in combustion. In the past when the assimilated air is sent into the air, the air pipe is constructed with a water trap to drain the condensate water. The anti-corrosion fan should also be selected for fan selection. After premixing, the assimilation air box is arranged in the fan. The historical circulating fan and fresh air of the fan are assimilated and sent to the burner for combustion. The commissioning conditions of the fan shall be in accordance with the premixing state. However, a large amount of condensate will be produced in the air duct, so the steam catcher should be built at the low point of the assimilation bellows and the flue gas duct.
The integrated control system is the advanced control mode that we put forward earlier today. In Europe and the United States, there are few limited industries and Chinese enterprises are required to choose this control concept. Its core idea is to program the control of boiler and burner in a unified way, and to hold accurate digital control. This control mode avoids the shortcomings of the original control methods, such as: dispersion, incompatibility, and multiplicity Problems such as point to point disposal, economy, etc.
Its advantages are as follows:
Software compatibility optimization, electronic control uniformity, greatly forward control accuracy, energy saving and consumption reduction
Decision making and manufacturing consistency, safety reliability and manufacturing cost savings
Single HMI dialogue
Control system intuition
Forward innocence, tranquility
Single professional debugging to ensure safety and efficiency
The continuity of one-stop after-sales service greatly advances the work compliance and lowers the service cost of users
Guarantee one touch accessories, software and upgrade
