Generally, 10-ton gas hot water boiler refers to the heat of evaporating one ton of water to steam coal. its heating area has regional differences, heating 50 ~ 70W per square meter, and its heating area varies. The heating area is from 6000 to 10,000 square meters. Now some regions also stipulate 32W per square meter, 32W can be used for nearly 15,000 square meters, there should be a margin in the specific design.
The height of the house, the size of the space, the thermal insulation performance, the layout of the pipe network, etc., have a great impact on the heating area of the boiler. Taking a gas hot water boiler as an example, we will introduce to you the heating area of a 10-ton gas hot water boiler and how much it will cost to operate.
Taking the consumption of 10 tons of WNS7 gas-fired hot water boiler as an example: 600,000 kcal / hour ≈ 1 steam ton / hour (t / h) ≈ 0.7 MW (MW), 10 tons = 7 MW
Model: WNS7
Rated thermal power: 7mw
Rated water pressure: 1MPa
Rated outlet temperature; 95 ℃
Rated inlet temperature; 70 ℃
Natural gas consumption; 753Nm³ / h
Transport size; 6373 * 2640 * 3126mm
Generally speaking, in the northern district heating, a 1 ton boiler heating area is 6000 square meters, and the southern district heating can reach 8,000 square meters. The heating area of a 10-ton gas hot water boiler ranges from 600,000 square meters to 800,000 square meters. The thermal efficiency of Zozen WNS series hot water boilers is above 95% and the circulating water capacity is 240t / h. In terms of performance, it has the following characteristics:
1. Low cost:
The implementation of the West-East Gas Pipeline reduced the price of natural gas and reduced fuel costs; this type of boiler has high combustion efficiency, saves fuel, and has low investment costs for purchasing fuel; full-edge butt welds, long boiler life and low maintenance costs
2. High efficiency:
The tail is equipped with a flue gas condensation recovery device, which can effectively control the exhaust temperature, and the boiler has high thermal efficiency; a fully automatic burner is used, and the feed water is continuously and electrically adjusted for high combustion efficiency.
3. Safe and stable:
Designed with over-temperature, over-pressure, water shortage, leak detection, flameout and other protection functions, the boiler runs safely and reliably.
4. Save space:
Adopting a quick installation structure, the entire boiler is designed on a very rigid base, which is easy to install and transport, which saves space in the boiler room.
Operating costs:
The natural gas consumption for a 10-ton hot water boiler is 70m³ / h, the natural gas price is 3.7-4 yuan / m³, and the natural gas cost is 259-280 yuan.
The factors that affect the heating cost of a 10-ton gas hot water boiler are as follows:
1. Fuel calorific value;
2. Fuel prices;
3.Boiler thermal efficiency
4.Boiler heating area
5. Boiler installation capacity;
The above is the operating cost of a 10-ton gas hot water boiler, plus labor costs and other controllable expenses, which is about the cost of a piece of equipment during operation;
