Design scheme of gas hot water boiler
Option 1: 19 DW-1810 Smith Smith DC gas hot water boilers;
Plan 2: 4 WNS2.8-0.7 / 95 / 70-YCQT Sino-Japanese joint-venture gas-fired hot water boilers.
Analysis and comparison of the operation of the two schemes: The following is an analysis of boiler operation with a building area of ​​150,000 square meters as an example. The number of heating days in winter is 120 days per year, and it can be divided into three stages according to the situation in Beijing:
The first phase is from November 15 to December 24. At this time, the climate is characterized by Beijing's early winter season, and the temperature has not changed much since the beginning of winter.
From December 25 to February 4 is the second stage. At this time, the climate is characterized by rapid temperature changes, and the temperature is the lowest point of the average year, which is the season with the largest heat consumption.
February 5 to March 15 is the third stage. At this time, the climatic characteristics are similar to the first stage. The temperature rises after the severe winter. The temperature at night is around 0 ℃. Especially in March, the daytime temperature is mostly around 10 ℃. When heat consumption is minimal.
(1). 19 Smith module boilers are in operation, and the boiler working conditions are calculated according to 120 days in winter, and 120 days are divided into three stages on average, and each stage averages 40 days.
The first and third stages are early winter and early spring gas in Beijing. Four boilers are started and the average operation time is 9 hours per day. The price of natural gas is 1.9 yuan / m3, and the operating cost is 14 units × 80 days × 9 hours / day × 53.6m3 / H Taiwan × 1.9 yuan / m3 = 1026547.2 yuan
The second stage is the coldest season in Beijing, with 19 boilers started and an average of 12 hours of operation per day. The price of natural gas is 1.9 yuan / m3, and the operating cost is: 19 units × 40 days × 12 hours / day × 53.6m3 / H · unit × 1.9 yuan / m3 = 928780.8 yuan. The annual average operating cost is: 1. Annual heating gas cost: 1026547.2 yuan +928780.8 yuan = 1955328 yuan. 2. The annual heating area fee: 1955328 yuan ÷ 150000㎡ = 13.04 yuan / ㎡.
(2), 4 WNS2.8-0.7 / 95 / 70-YCQT Sino-Japanese joint-venture square gas hot water boilers. The 120 days are divided into three stages on average, and each stage averages 40 days.
The first and third phases are early winter and early spring gas in Beijing. Three boilers are started and the average operation time is 8 hours a day. The price of natural gas is 1.9 yuan / m3. The operating cost is: 3 units × 80 days × 8 hours / day × 317m3 / H · Taiwan × 1.9 yuan / m3 = 1156416 yuan
The second stage is the coldest season in Beijing, with 4 boilers started and an average of 12 hours of operation per day. The price of natural gas is 1.9 yuan / m3, and the operating cost is: 4 units × 40 days × 12 hours / day × 317m3 / H · unit × 1.9 yuan / m3 = 1156416 yuan The annual average operating cost is: 1. Annual heating gas cost: 1156416 yuan + 1156416 yuan = 2312832 yuan. 2. The annual heating area fee: 312832 yuan ÷ 150000m2 = 15.42 yuan / ㎡.
To sum up the analysis: according to the situation, you can adopt the lower square boiler with initial investment; you can also choose the Smith boiler with lower operating cost. Due to the low operating cost and energy saving of modular boilers, we recommend the use of Smith modular boilers.
Editor's summary: As ordinary consumers, we must choose and determine the correct operation plan before choosing our own gas hot water boiler, so as to carry out specific construction, only in this way can we spend the least money to buy The most suitable gas-fired hot water boiler.

For the meat marinating solution we refer to meat tenderizer, Saline mixer, Saline injector(brine injection systems), vacuum massage tumbler.
Saline injector can evenly inject the brine and salt auxiliary materials into the meat blocks, which can shorten the pickling time and greatly enhance the taste and yield of the meat products. The machine can be adjusted with stepping rate, stepping distance, injecting interval and injection pressure according to the technological requirements. Then the brine and salt auxiliary materials can be injected into the meat evenly and continually to reach the optimal effects.
While vacuum tumbler makes meat rolled in the drum under vacuum condition, similar to pulmonary respiration (make product to inflation and shrink alternatively). It makes meat salted evenly, increases the adhesive quality and taste and ensures the freshness of meat.
