Vacuum hot automatic fill water boiler how to discharge of sewage (1) inside the drain valve opened; (2) Slowly drain valve opened outwardly, a discharge duct and the warm water; (3) back and forth from the closed and open outwardly the drain valve, flush slowly furnace debris so far as possible emissions; (4) inside the drain valve closed, between these two stored water drain valve discharged; (5) outwardly closing the drain valve, sewage discharge is terminated.

Overview of 4 ton Chain Grate Coal Fired Steam Boiler

4 ton/h Chain grate coal fired boiler is independently developed by ZG Boiler as the fourth generation horizontal water tube and fire tube packaged boiler in 1980’s, with completed and developed for the last 30 years, the boiler has the features of small occupation, bigger output, quick pressure, high efficiency and so on.

4 ton/h Chain grate coal fired boiler for sale in ZG Boiler is a kind of chain grate boiler, it adopts advanced technology invented by Xi’an Jiaotong University, which make the lean coal combustion easier and it can adjust itself to a wide range of coal types.

In mid-March this year, Shenyang City, the first boiler industry issued emission permits. Plan will livestock poultry, dairy products manufacturing, automobile manufacturing and other industries 29 issued emission permits, issued by the maturity shall not sewage, sewage behavior of errant card companies to investigate and punish. This is also the industry's first Shenyang boiler emission permits.

According to the State Department "to control emissions permit system implementation plan" and the Ministry of Environment "discharge permit management approach", 2017 in Shenyang City has completed thermal power, paper, cement, electroplating, pharmaceutical, pesticide, textile printing and dyeing industry, 54 enterprises license issuance of work. 2018, the city completed the issuance of emission permits 128, including iron and steel industry 5, slaughtering and meat processing industry 106, 16 water treatment industry, ceramic industry one, according to industry certification and time-bound national requirements, so that " should be sent to do hair. "

This year, Shenyang City, according to "stationary sources of pollution permits Classification Catalog" requirement, will be livestock poultry, dairy products, Condiments fermentation products manufacturing, food manufacturing other convenience food, wine manufacturing, footwear, plywood manufacturing, bamboo and rattan wood furniture manufacturing, polyvinyl chloride, phosphate fertilizer, automobile manufacturing, battery manufacturing, non-metallic waste and scrap metal processing, garbage to hazardous waste sludge as fuel for thermal power generation, sewage treatment and recycling, environmental control industry , heat production and supply, electroplating facilities, sewage centralized treatment of industrial waste water and other 29 industries issuance of emission permits. Up to now, has been launched boilers, water treatment, ceramics, automobile manufacturing, battery manufacturing, phosphate fertilizer industry and electroplating processes work permits issued.

Shenyang Ecological Environment Agency, responsible person, emission permits to take "a card-style" management, so that all the laws and regulations of the environmental requirements of an enterprise integration to a convergence of the proposed permit up to implement the main responsibility for polluters. A company issuing a discharge permit, enterprises through the establishment of self-commitment, self-monitoring, accounting records and regular reporting system has proven its emissions by law, to further strengthen fine management.

Shenyang in the discharge permit issued during the EIA procedure will be incomplete, excessive emissions, there is the issue of corporate environmental management ordered rectification to achieve "issued an industry, to clean up an industry, an industry specification, an industry discharge standards." In the future, Shenyang will be implemented in accordance with the regulatory card issuing companies to carry out law enforcement inspection post card, after intensive license management, enterprise undocumented sewage discharge permits and do not follow the behavior will be investigated according to law.

Apart from these efficiency, there are some other losses which also play a role while deciding the boiler efficiency and hence need to be considered while calculating the boiler efficiency. However, the most important factors need to be considered are boiler combustion efficiency and boiler thermal efficiency.
