lng hot oil boiler slaughter plant
6MW YQW series gas-fired thermal oil heater project for food industryThe rapid development of the food industry is inseparable from the strong support of the lng hot boiler slaughter plant system, which is one of the important production line equipment for the plant extraction process. Founded in 1995, Damin Food (Zhangzhou) Co., Ltd. is an international enterprise group specializing in deep processing of natural plants which integrates R&D, production and sales. Its products are exported to the United States, Japan, Europe and other countries and regions. It is an international supplier of many large-scale food and beverage, restaurant chain and health care products pharmaceutical companies.Damin Foods is committed to producing healthy and natural products and creating a healthy lifestyle that returns to nature. Therefore, Damin Foods attaches great importance to its own green development, and adheres to the environmental protection concept in the selection of boiler equipment. It plans to introduce environmentally friendly boilers that use clean energy natural gas as fuel. After understanding their actual needs, ZOZEN tailored the technical solution for Damin Foods: newly construct four sets of 5 million kcal YQW series thermal oil heaters. This series of gas-fired thermal oil heaters has the characteristics of high temperature and low pressure. In the process of plant extraction, high temperature steam is used to complete the sterilization process of plant concentrate, which fully meets the temperature requirements of Dagu food production line. The tail of the heater is also equipped with waste heat recovery devices. By recycling the waste heat of high-temperature flue gas, the heat energy loss is greatly reduced, and the overall thermal efficiency of the heater is increased to over 95%.
Industrial production is inseparable from lng hot boiler slaughter plants, emission control of atmospheric pollutants boiler air pollution control in Shanghai to expand and intensify the focus of the project. Currently, Shanghai Industrial boilers alternative clean energy has been completed, nitrogen oxides (NOx) emissions of major pollutants as a boiler, the boiler due mostly low shelf emission source of ambient air near the ground and ozone greater PM2.5 influence, therefore, this release the new standard, the boiler will be low-nitrogen transformation, improve Shanghai air quality, protect people's lives and health and other aspects demand a strong thrust of great significance. Throughout the country, Beijing, Tianjin and other places have started low-nitrogen transformation boilers for low-nitrogen transformation has a more mature technology reserves. Based on the above considerations, for the effective control of NOx emissions from boilers, to further deepen cooperative control of PM2.5 and ozone, according to the standard first, to further accelerate the transformation of governance principles, it is necessary once again to revise the standard boiler.
According to local environmental standards and revision procedures, the Municipal Environmental Protection Bureau held a meeting to hear the relevant departments, enterprises and the opinions and suggestions of experts, and in 2017 August 4 to September 15 in the online open standard full text to solicit public opinion. At the same time the Ministry of Ecology Environment solicit written opinions Municipal Development, City Commission by letter and other related commissioned Bureau, industry organizations and boilers, production units and other enterprises. Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision on January 19, 2018 organized the expert technical review meeting, the panel agreed that standards through technical review. Approval by the Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision audit report to the municipal government.
The new standard has been revised for several aspects, one is no longer on the "central heating boiler and the nominal amount of evaporation less than 65t / h boiler cogeneration" provisions alone time; the second is to simplify the original class standard boiler merged into " gaseous fuel boiler "and" boilers "categories; are three different degrees of contamination tightened limits particulate matter, sulfur dioxide and nitrogen oxides; four new boiler is implemented from the date of implementation of this standard, the boiler given a transition period of about two years.
New standards for gaseous fuel boiler particulate matter, sulfur dioxide and nitrogen oxides are applied strict limits, but mainly considering the control of nitrogen oxide emissions, and further improve air quality. In the transition period boiler (1 October 2020) to limit nitrogen oxide 150mg / m³; after a transitional period of 50mg / m³. Date of implementation of new boiler nitrogen oxides from standard starting execution 50mg / m³ limit. Taking into account the comprehensive utilization of straw in Shanghai, biomass fuel boilers follows the standards of the original project control and limit requirements.
Why fuel gas-fired lng hot boiler slaughter plant will turn off? Although the case of gas-fired boiler fuel oil dual boiler, but only that the furnace can be gas fuel, but a normal customer choice is to select a class of the final fuel only, even if a mixed gas, also belong to the category of gas.
Burner output should match the rated output of the lng hot boiler slaughter plant, choose a good shape of the flame, such as length and diameter so as to adapt the furnace structure. The required combustion air is supplied from the root flare fuel gas and air or oil mist uniformly mixed rapidly, to ensure complete combustion.
