In a hotel with 240 people, how big a gas-fired hot water boiler should be used for bath hot water? Who knows? Do the math. thank you

1. Hotel conditions: 1) There are 60 single rooms, 70 standard rooms and 40 economy rooms, which provide guests with hot water for bathing. 2. Selection calculation: the water consumption for bathing per person is about 80L, and the water temperature is 45℃. When the hotel is full, the total water consumption for each guest to take a bath once a day is: (60+70 * 2+40) 80l =19200l =19.2 tons. According to the calculation of calorific value, when the temperature of 1℃ rises, the heat absorption capacity is 4.2 * 10 3j = 1 kcal. It is known that the water consumption of hot shower water in standard room is 19200kg/ day. The water temperature is 45℃. Assume that the lowest inlet water temperature is 5℃ in winter. Then the total heat input of hot water for bathing in this hotel every day is: Q = 19200× (45-5) = 768000 kcal/day = 768000 kcal/day. Considering the heat loss caused by pipeline cooling and other factors in actual use, the actual daily heat demand of the hotel is about 800 thousand calories/day. Boiler and water tank are used to provide hot water, and the utilization coefficient is 0.7 (that is, all rooms 1 person take a bath at the same time), then: 80 * 0.7 = 560,000 calories/hour. Three. Type selection needs 19.2 tons of hot water every day, so it needs 19.2/24=0.8 tons per hour. To be on the safe side, choose 1 ton boiler. You can check the boiler parameters, and choose 1 ton boiler, with a heating capacity of 560,000 kcal/hour. 1.
