Price of gas-fired hot water boiler

Generally, the price of gas-fired hot water boiler should be around 6.5438+0 million yuan. Because there are many models of this kind of boiler, ranging from thousands, tens of thousands to hundreds of thousands of products. Design scheme of gas-fired hot water boiler

Scheme 1: 19 DW- 18 10 American Smith once-through gas-fired hot water boiler;

Scheme 2: 4 WNS2.8-0.7/95/70-YCQT Sino-Japanese joint venture box-type gas-fired hot water boilers.

Analysis and comparison of the operation of the two schemes: take the building area 150000_ as an example to analyze the operation of the boiler. The annual heating days in winter are 120 days, which can be divided into three stages according to the situation in Beijing:

165438+1October15 ~ 65438+February 24th is the first stage. The climate at this time is characterized by the early winter season in Beijing. Just entering the winter, the temperature has not changed much.

The second stage is from February 25th to February 4th. 10. The climate at this time is characterized by the rapid change of temperature, which is the lowest point every year on average, and it is the season with the largest heat consumption.

The third stage is from February 5 to March 15. The climate characteristics at this time are similar to those in the first stage. After the severe winter, the temperature rises, and the temperature is around 0℃ at night. Especially in March, the daytime temperature is mostly around 10℃, which is the time of minimum heat consumption.

When the (1) 19 Smith modular boiler is running, the winter working condition of the boiler is calculated as 120 days, and 120 days is divided into three stages on average, with an average of 40 days in each stage.

The first and third stages are the weather in early winter and spring in Beijing. The four boilers start running for an average of 9 hours every day. Natural gas price 1.9 yuan /m3, operating cost 14×80 days× 9 hours/day× 53.6m3/h×1.9 yuan /m3 = 65438.

The second stage is the coldest season in Beijing, starting boilers 19 units, with an average daily operation of 12 hours. The price of natural gas is 1.9 yuan /m3, and the operating cost is19× 40 days × 12 hours/day× 63.6m3/h units. The annual average operating cost is 1, and the annual heating gas cost is 1026547.2 yuan +928780.8 yuan = 1955328 yuan. 2. Annual heating area charge: 1955328 yuan150000 _ =13.04 yuan/_.

(2) Four WNS2.8-0.7/95/70-YCQT gas-fired hot water boilers in the Sino-Japanese joint venture plaza. Divide 120 days into three stages on average, and each stage has an average of 40 days.

The first and third stages are the weather in early winter and early spring in Beijing. The three boilers start running for 8 hours every day on average. The price of natural gas is 1.9 yuan /m3, and the operating cost is 3× 80 days× 8 hours/day× 317m3/h×1.9 yuan /m3 = 65438+.

The second stage is the coldest season in Beijing. Four boilers are started, and the average daily running time is 12 hours. The price of natural gas is 1.9 yuan /m3. The operating cost is: 4× 40 days×12 hours/day× 317m3/h×1.9 yuan/m3 =1156416 yuan. The average annual operating cost is: 1. 2. Annual heating area charge: 3 12832 yuan150000m2 =15.42 yuan/_.

To sum up, according to the situation, square boilers with low initial investment can be used; Smith boiler with lower operating cost can also be selected. Because of the low operating cost and energy saving of modular boiler, we suggest adopting Smith modular boiler.
