water tube coal fire presses boiler

35 tph SZS gas-fired water tube water tube coal fire presses boiler project for dairy industryPlenty of steam is needed in the milk powder production process of sterilizing, concentrating and drying; therefore, a stable steam boiler has a direct impact on the milk production quality. Heilongjiang Feihe Dairy Industry Co., LTD., established in 1962, has won the Gold Award of Monde Selection. As hazy weather appears frequently in recent years, air quality issues have aroused great concern of the whole society. The Chinese government has successively launched "coal to gas" and other environmental policies to improve the air environment. Feihe Dairy is taking an active part in environmental protection, the company decided to replace the present 2 sets of 35 tph coal-fired steam boilers and one set of 20 tph coal-fired boiler with 3 sets of 35 tph gas-fired steam boilers. Considering that the steam boiler is a core equipment of the production line, the company had attached great importance to this purchase and held an open tender. ZOZEN successfully won the bid with excellent product quality and service, and provided the company with 3 sets of SZS series gas-fired steam boilers. This series of boiler adopts the design of membrane water wall; the gastight test must be done before installing thermal insulation layers, to ensure there is no flue gas leak under the condition of micro-positive pressure combustion and help reduce the heat loss of the boiler body. In addition, to effectively reduce the NOx emission, the boilers are equipped with large volume furnaces and advanced low NOx burners imported from Europe.

To complete the "clean winter heating pilot cities in northern areas," the goals and tasks, Jinan Municipal People's Government issued the "Jinan City" pilot cities for winter heating cleaning northern "three-year implementation plan (2017-2020 years)." "Program" is mentioned, three-year pilot period 59 key projects a total investment of 27.3 billion yuan, 2.1 billion yuan from the central government funds, municipal funds 5.8 billion yuan financial support to attract social capital of 19.4 billion yuan. Six technical work in accordance with the deployment path, focusing on elimination of coal-fired water tube coal fire presses boilers, clean the deep geothermal heating, urban and rural construction and other clean energy alternative to lead technical projects, improve the maintenance of post-operation, promote clean winter heating work in an orderly manner.

Focus on the implementation of urban and rural clean energy alternatives. In the vast rural areas and central heating uncovered areas, in accordance with the enterprise-based, government promotion, residents affordable policy, local conditions, the use of alternative energy classification implementation. Urban and rural clean energy alternative to task a total of 48 projects, plans a total investment of 6.272 billion yuan (excluding clean coal-burning alternative to low-quality coal project), in which the central budget funds 820 million yuan, local financial and social capital invested 5.452 billion yuan. Coal to electricity which involves 19 projects, the use of alternative energy, Valley Electric energy storage, energy management contract, support clean green electricity for heating, with a total investment of 650 million yuan, of which the use of the central budget funds 250 million yuan; shed no change change clean heating, involving 95 000, in which the central government 200 million yuan.

At present several common water tube coal fire presses boiler energy-saving technologies: usually for boiler manufacturers, it means that you are saving boiler to maximize the interests of customers, providing customers with unlimited fuel savings, the electricity consumption, water consumption and so on. But the wide range of energy-saving, does not refer to an aspect of optimization can save energy boilers, here's a look now common boiler energy-saving technologies: 1 furnace arch. Industrial boiler furnace arch is very important. Arch role is to cause the furnace hearth and the organization of the mixed gas and the radiation hot flue gas flow, ignition and combustion of the fuel in a timely manner. At present, the actual amount of industrial steam boiler with its rated load often do not match, the use of coal varies widely, but often with the design coal are quite different, so in actual use, often as necessary for the furnace arch modified to meet the needs of coals. Heteroaryl coal used by the inferior design coal, the boiler furnace exit gas temperature occurs is low (about 700 degrees), lower than 200 degrees design.

Efficiency Efficiency water tube coal fire presses boiler fuel oil-fired boiler (1) and the threaded pipe arch tube plate consisting drum, the drum so that a quasi rigid body variant subject elastomeric structure, the bracing member canceled tube sheet area, reducing stress. Smoke tube consists of two single backhaul backhaul to solve the problem of cracking of the tube plate. (2) a lower drum rise due to the arrangement of the discharge tube, eliminating dead zones at the bottom of the drum, so that there is less deposit sludge, drum high temperature region can be obtained good cooling, preventing the lower portion of the boiler drum package boiler shell. (3) use of efficient heat transfer threaded pipe, the heat transfer enhancement effect is obtained, heating the boiler to reach fast boosting features improve the thermal efficiency of the boiler. (4) stable, easy adjustment, contribute enough. It has 110% overload capacity. (5) hot water boilers have been major improvements in the water cycle. Successful use of jet technology, the purpose of the return water jet enters the downcomer, to improve the cycle rate of the riser. (6) The threaded pipe enhanced heat transfer, the heat transfer coefficient and improve thermal efficiency, since there is disturbance in the flue gas pipe, hard fouling smoke tube, play a role in self-cleaning. (7) use of energy efficient furnace furnace arch integrally cast heat resistant concrete, improved coal fire conditions, uses a separate plenum, to achieve reasonable air distribution, forming a favorable aerodynamic field of combustion in the furnace, whereby expand the adaptability of coal. Furnace arch (8) of the boiler, there is a certain part of the outlet smoke dust window effect. The original boiler control dust emission concentrations below the standard, to ensure that the indicators boiler soot emissions meet the national environmental regulations.
