Recently, the State Administration of China's market, the National Development and Reform Commission, Ministry of Ecology Environment jointly issued the "Notice on Strengthening Environmental Protection and Energy cheap boilers south africas" (the "Notice"), put forward specific requirements for environmental aspects of energy-saving boiler work.

"Notice" the implementation of the guidance, "the CPC Central Committee and State Council on the overall strengthening of environmental protection and resolutely fight tough fight pollution prevention advice" and other documents, adhere to safety first, prevention first, the five principles of energy saving, comprehensive management implement energy saving boiler from the production, import, sale, use and other aspects of business to post the main responsibility, and strengthen supervision and management of Eng environmental Protection in the "special equipment Catalog" range of boilers, and comprehensively promote energy-saving environmental governance boiler.

First, across the country, in principle, to a new 10 steam tons / hour of coal-fired boilers and, in key areas (and the surrounding areas of Beijing, Tianjin, the Yangtze River Delta region and Fenwei plain) and the rest of the city built the county level and above New District, in principle, to 35 tons of steam / hour of coal-fired boilers.

Second, the new coal-fired boiler emission concentration of air pollutants key areas need to meet ultra-low emission (6% on the basis of the reference oxygen, soot, sulfur dioxide, nitrogen oxides emission concentration of not more than 10,35,50 mg / m) requirements.

Third, the area reserved execution key boiler air pollutant emission limits or special places more stringent emission standards, 65 t steam / hour coal-fired boiler and above all of the ultra-low emissions and energy transformation embodiments, a low nitrogen gas boiler is substantially complete transformation.

"Notice" also stressed the upgrade boilers with energy and environmental conservation requirements. Boiler units to implement the main responsibility for ensuring that the boiler energy efficiency and emissions of air pollutants meet legal regulations, technical specifications and requirements of the relevant standards in China.

Fourth, for the boilers do not meet environmental requirements, and use shall take appropriate measures for improvement, if after rectification not meet the requirements, be allowed to continue to use.

Fifth, the boiler unit to apply for emission permits in accordance with laws and regulations, and to establish their own monitoring system, strict discipline and preservation of the environment management accounting, timely and relevant departments to prepare and submit emission permits implementation report.

Sixth, the boiler unit to promptly take the initiative to report the boiler equipment obsolete, and apply for cancellation of the boiler use registration shall not be obsolete boilers to move equipment or put into use again.

Excessive moisture content in steam cheap boilers south africa steam boiler steam system of hazard in the event of excessive steam water content, will constitute a steam system damage. Steam boiler system in major damage to wet steam are: 1, water droplets suspended in the steam pipeline corrosion can drop life. Replacement pipe is not as long as the cost of materials and labor, and you want some pipeline closed for repairs, it will bring some loss of production. 2, the steam contained in the steam boiler system, water droplets can damage (corrosion of the valve seat, the valve body) the control valve, so that the effect of lost, and eventually damage the quality of the goods. 3, the steam contained in the water droplets will collect on the exterior of the heat exchange water into a thin film growth. 1mm thick film of water corresponding to 60mm of iron / steel sheet or 50mm thick copper plate heat transfer, this layer of water film to change the appearance of the heat exchange coefficient of the heat exchanger, the heating time is extended, decreased production capacity. 4, wet steam with decreased total gas heat exchange device power. Water droplets occupy valuable space means boring full steam vapor will be taken to effect heat transfer. 5, the wet steam in a steam boiler system in concealing mixture of fouling in the heat exchange outer, heat exchange will decrease power. Heat exchange outer layer scale is not the same thickness, which causes different thermal expansion, a crack will occur on the outer heat exchanger. The material is heated from the condensate mixed with leak cracks, loss soiled condensate, will bring about high costs. 6, the wet steam concealing mixture control valve and steam trap fouling, will affect the operation of the valve, to add the cost of repairs. 7, wet steam boiler system, steam heating the product mixture enters the concealing eruption of steam directly, if the product requires high hygiene standards fit, becomes contaminated waste products will not be sold. 8, some processing technology is not wet steam, wet steam will eventually affect the quality of the goods. 9, in addition to the influence of the apparent power of the heat exchange outer wet steam, wet steam concealing will constitute excess water trap and condensate recovery system overload. Traps overload will condensate back, if condensed water vapor occupies space, which will reduce production capacity of processing equipment, during this period will ultimately affect the quality of the goods. 10, water droplets in the steam, air and other gases can affect the accuracy of the flow meter measuring the flow rate. Dry steam coefficient is 0.95, the configuration of the flow measurement error of 2.6%; and boring coefficient is 8.5, the measurement error will reach 8%. Means for supplying steam flow is accurate reliable data to an operator, the production technology for the process control in the best condition and to maximize the production of power, steam and water droplets so that all can not be accurately performed.

20 tph SZL biomass-fired water tube cheap boilers south africa project for oil refining industrySteam boilers are used for refining, bleaching, deacidification, deodorization, fractionation and other processes in the palm oil production. PT.Mikie Oleo Nabati is an Indonesian company established in 2001. The company’s main activity is to process CPO into various products like PFAD, RBD Palm Oil, RBD Stearine, RBD Olein (Cooking Oil) & Margarine. Steam boilers play an important role in their production. The original biomass-fired boilers used by them easily have the problems of scaling, abrasion, burning front arch and feeding hopper, which affect their production lines seriously. The biomass-fired boilers made by ZOZEN can perfectly resolve the problems mentioned above. Therefore, PT.Mikie Oleo Nabati has planned to order several sets of ZOZEN’s quality biomass-fired boilers. Taking the fact that palm shell is used as the fuel by this refinery into consideration, ZOZEN’s professional engineer has made an optimization design for length and width of feeding hopper, rotary speed of gearbox, 1st and 2nd air ratio, etc., to guarantee the sufficient combustion and improve the thermal efficiency. The thermal efficiency of ZOZEN’s biomass-fired boilers can reach above 88%.
