mechanical natural gas hot water vacuum fire tube boiler price

Harbin Thermal Power Co., the main city of Harbin is the largest cogeneration business, the company bear the city's heating area of ​​24 million square meters, to provide heat supply for more than 400 agencies, enterprises and 140,000 residents. Currently, the company is actively respond to the latest environmental standards introduced in China, the group mobilized up and down, stepping up technological innovation, upgrading environmental protection facilities, the project is expected to complete upgrading coal-fired boiler at the end of this year.

Harbin Thermal Power Co., the existing five boilers for heating and power generation: where to cogeneration units No. 7,8,9, and the other two hot water boilers. No. 9350 MW units which since 2017 was completed and put into operation, has achieved ultra-low emissions standards during construction. 7, No. 8 is 300 MW units were built in 2005 and 2006, these two units of environmental transformation began in 2013. Harbin Thermal Power Co., according to the latest environmental requirements, environmental upgrading facilities. First, soot emissions transformation, the introduction of advanced electric bag filter, followed by addition of sulfur, in addition to the transformation of nitrate, new burners in addition to the low nitrogen oxides of nitrogen, a wet desulfurization technologies in addition to sulfur dioxide. After four consecutive years of continuous transformation, 7,8 units in 2017, all the transformation is completed, achieve ultra-low emissions standards. For the two 116 MW hot water boiler was built in 2013, it has long been included in the transformation plan. Earlier this year preparatory work has been completed and environmental transformation has entered the bidding process in mid-October to start construction, completed renovation project at the end of December.

Traditional industrial boilers difference is that the internal pressure of the vacuum boiler is less than the ambient pressure (vacuum food you can think of), mainly used for hot water output. This is because in the case of reduced pressure, the boiling point of water is also reduced, so that at low temperatures can be done quickly boil.

"Vacuum" refers to an automatic vacuum apparatus and the pressure inside the boiler is lower than the outside atmospheric pressure is low with water a low boiling point characteristic, rapid heating of the heat medium water, increase the heat transfer rate.

What is the main operation of steam boiler used in food processing industry

Steam boilers are often used in the food processing industry for the processing of various foods, especially bread and dairy products or biscuits, which are used more frequently by enterprises. Because the professional steam boiler has the good heat energy conversion and stable operation ability, the use in the food processing industry not only can help the enterprise to complete the efficient processing operation, Food can also be kept clean and clean to achieve environmentally friendly processing. The following editor will lead you to understand the main operation projects of the food processing industry using steam boilers:

1, the cooking food industry often needs a large amount of cooking to achieve the processing of cooked food, and through steam boilers, it can quickly and effectively complete the operation of cooking different foods. The processing quality of food is very high, especially for sanitary cleaning. Therefore, only the steam boiler with high environmental protection and no pollution can meet the needs of the skimmers.

2, the distillation of many foods in the processing process also requires effective distillation operations, distillation is the steam boiler to effectively separate the various moisture in the food. Operating distillation in a high vacuum boiler can not only ensure the original taste of food, but also quickly separate all kinds of moisture from each other in the food, so as to prepare for the next processing operation of the food.

3, sterilized and dried foods such as biscuits or bread and dried meat need to be sterilized and dried, and can not be separated from the operation of a steam boiler, and the high-temperature steam advantage of the boiler can be used to quickly steam the food at a high temperature. After the steamer is good, the food is dried and sterilized to meet the finished product standard. The use of steam boiler is not only safe and easy to control temperature and pressure, but also avoid the undesirable phenomenon of over drying or high moisture content in food processing.
