In recent years, Ningbo municipal government attaches great importance to environmental protection, air pollution prevention and control work to strengthen the organization and leadership, the establishment of a multi-sectoral collaboration to air quality at the core of the atmospheric environment management systems. And introduced a new quality of atmospheric environment deadline for compliance plan, as follows.

Strict implementation of total coal consumption control, to further optimize energy consumption structure, strive to 2020, coal consumption accounts for the proportion of primary energy consumption control in about 40% of coal consumption is not higher than 2011 levels, and completely cut coal province issued the task .

Strengthen management work focused on coal-fired projects, continue to promote the elimination of the transformation of small coal-fired boilers. 2019, phasing out 10 steam tons / hour of coal-fired boilers and, in 2020, the county level and above urban area basically eliminated tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities; basically eliminated the city's 10 -35 steam t / h coal-fired boiler; 35 t steam / hour and more polluting fuels and ultra-low emissions energy boilers complete transformation.

Strengthening coal quality control, within the city limits the use of ash> 16%, sulfur> 1% low-quality coal, fuel encourage high value, low sulfur, low ash blending works. 2019, the establishment of the city's coal regular testing, sampling tests system. In 2020, the city's clean coal utilization rate of 90%.

Increase natural gas use, and actively promote major infrastructure construction official website of natural gas, LNG receiving station and other utilization of natural gas, natural gas Daly improve utilization levels.

Enhance the energy efficiency of industrial enterprises. Actively promote advanced energy conservation projects integrated coal demonstration projects, large-scale generating units coal consumption reached the advanced level of the same type of unit.

Development of central heating, central heating project to optimize the layout, promote industrial parks focused on central heating. Focus on industry gathering area, industrial park development of cogeneration, and encourage qualified development of thermoelectric cooling area for the triple. Further improve the matching of heating pipe network, construction of efficient, fast heat pipe network. 300,000 kilowatts and above cogeneration power plant 15 kilometers behind the small coal-fired boilers and coal-fired thermoelectric heating within a radius of all closed down integration.

A main component composed mainly of gas boiler gas boiler: the combustion chamber collector, collector, oil, gas in one. A high degree of integration and automation of the boiler system to maintain focus. Boiler: boiler body is the main part of the thermal energy conversion computer control system: the computer control system is the core component of the boiler, the boiler is the command center. Each System Maintenance: Maintenance burner: Burner thorough cleansing of the rotor disk, the ignition device, filter, pump, motor and impeller system, add more oil to the air valve linkage means. Re-test burn conditions. Maintenance Controller: maintenance and testing electrical components, the control circuit, the control box cleaning fouling, detects for each control point. Finally, a sealing process. Prevent moisture from the controller assembly. Water Supply System Maintenance: Maintenance of water treatment equipment, checking water quality standards, a comprehensive clean water treatment system, check pump operation and head to check the usage of each flexible pipe valves and so on. When the system is filled with water, and cut off the water supply, close the valve. Furnace Maintenance: In order to make long-term boiler safety, economic operation, it is necessary to strengthen the maintenance of daily use of the boiler. This is also an important measure to prevent the decline in thermal efficiency, in order to avoid the deterioration of conditions of service and boiler accident. Fertilizer agricultural production in the most basic and important material inputs. According to the Food and Agriculture Organization (FAO) statistics, accounting for crop fertilizer output increased 40% and 60%. 7% of the world's population in the world's arable land, fertilizers play an important role. You know how fertilizer is produced and processed it? Fertilizer production and processing of work can not be separated electric diesel steam generator. Fertilizer referred to as fertilizers. One kind of fertilizer made by chemical and / or physical methods, containing one or more nutrients required for plant growth. Also known inorganic fertilizer comprising nitrogen, phosphate, potash fertilizer, fertilizer and the like. Fertilizers wide range of different nature, different methods of administration. Complex fertilizer production is a continuous process, requiring high temperatures and pressures in a closed system in. Fertilizer fertilizer plant steam generator has become essential equipment, provides a high temperature and pressure steam environment for fertilizer production. Promote the smooth progress of the fertilizer production process in a series of reactions. Fertilizer production requires a variety of multi-step mechanical features, such as granulator mainly produces particles, the water reached the national standard fertilizer particles dryers, conveyor belt materials, packaging machines. Normal operation of these devices must be carried out with the premise that matches the electric steam generator. Complex continuous production process, many different aspects of the effect is lost in a thousand miles, all genuine technical and production quality are fundamental equipment. Intelligent electric steam generator is provided for the production of pressure and temperature to provide a suitable environment. The reaction may be provided at the same time the steam, the heat required for granulation, drying, packaging, etc., to save a lot of fertilizer plant production costs. The steam generator having an evaporator, temperature, pressure adjustable, energy efficient means imports burner, auto-ignition, exhaust heat recovery, thermal efficiency, lower operating costs, no smoke, no fire, economical energy efficient operation, low carbon , one-button operation, automatic operation and other advantages. Fuel gas-fired boiler as an alternative to highly polluting coal-fired boilers in the country has been more widely used. Oil and gas boilers are easy to use and people's lives, thus extending the life of the boiler.

CFBC boilers are generally more economical than AFBC boilers for industrial application requiring more than 75 – 100 T/hr of steam. For large units, the taller furnace characteristics of CFBC boilers offers better space utilization, greater fuel particle and sorbent residence time for efficient combustion and SO2 capture, and easier application of staged combustion techniques for NOx control than AFBC diesel steam generators.

Vietnam Biomass CFB boiler in Sugarcan Mill Technology

The prime technology for sugar mill cogeneration is the conventional steam-Rankine cycle design for conversion of fuel into electricity.A combination of stored and fresh bagasse is usually fed to a specially designed furnace to generate steam in a boiler at typical pressures and temperatures of usually more than 40 bars and 440°C respectively.The high pressure steam is then expanded either in a back pressure or single extraction back pressure or single extraction condensing or double extraction cum condensing type turbo generator operating at similar inlet steam conditions.
