Costs of Boiler for Various Capacities

May 14, 2020

Industrial boilers are widely used in various industries, such as heating, disinfection, bathing, distillation, drying, etc. Different industries have different capacity requirements for boilers. The following is the cost of several commonly used boilers.

 

2 tons natural gas boiler

  1. Fuel cost, natural gas consumption is 70 cubic meters, and the price of natural gas is calculated according to 3.5 yuan / cubic cube: 70 * 3.5 = 245 yuan.
  2. Water fee 2 tons of steam requires 2.2 tons of water, the water is calculated at 3 yuan / ton 2.2 * 3 = 6.6 yuan / hour.
  3. The electric power used in the calculation of electricity bill is (1.5kw + 2.2kw + 2kw) * 0.65 = 3.7kw, electricity bill 1 yuan / degree 3.7kw * 1 = 3.7 yuan / hour.
  4. Maintenance cost 1 ton gas steam boiler, maintenance cost 2000 per year, according to 365 days a year, 8 hours a day 2000/365/8 = 0.68 yuan / hour Labor cost One inspector is calculated according to the salary of 2000 yuan in January, one day Working 8 hours 2000/30/8 = 8.3 yuan / hour The total cost is 245 + 3.7 + 6.6 + 8.3 + 0.68 = 264.28 yuan / hour.

Total operating cost of 4 tons of coal-fired steam boiler

Coal-fired steam boilers are mainly used in the chemical and food industry. Customers in Jiangxi asked how to calculate the cost of a 4-ton coal-fired steam boiler. First, let ’s take a look at the relevant parameters of Zhengzhou Boiler Factory:

  1. Steam capacity: 4 tons of saturated steam per hour.
  2. Steam pressure: 13 kg saturated steam pressure. 16 kg, 25 kg pressure is similar.
  3. Thermal efficiency: thermal efficiency 78%
  4. The price of fuel coal: the calorific value of coal is 5,000 kcal (based on actual conditions), and the price of coal is 600 / ton.
  5. Tonnage of coal consumption: The coal consumption for steam production is: 600,000 kcal / 0.78 / 5000 = 153 kg.

The cost of use is 153 x 600 / 1000-91.8 yuan. The cost of producing 4 tons of steam in one hour at full load is 367 yuan.

10 tons natural gas boiler

  1. Gas consumption per hour for a 10-ton natural gas boiler, 600,000 kcal * tonnage / heat efficiency / fuel calorific value = 600,000 kcal * 10 tons / 95% / 8000 = 789.5m³ / h, adjusted according to Henan commercial gas price It is 3.7 yuan / m³, and the fuel cost is: 789.5m³ / h * 3.7 yuan / m³ = 2921.15 yuan.
  2. The general power consumption includes: burners, water pumps, electric control cabinets, water treatment equipment, etc. According to the data provided by engineers, it is about 100 degrees per hour, industrial electricity is 1 block per hour, and the power consumption of 10 tons of gas boilers is 100 yuan per hour.
  3. To produce 10 tons of hot water from a gas steam boiler requires 10-11 tons of water. The water price is calculated at 3 yuan / ton, so the cost is 30-33 yuan per hour.
  4. Many gas hot water boilers now use an automated management mode; each boiler only needs to be equipped with 1-2 furnace personnel. Based on the average salary of 2,500 yuan per person, 2 people * 2,500 yuan = 5,000 yuan / person.
