Cost of 4 Ton Boiler

April 17, 2020 Tags:

Under the condition of suitable transformation of coal-fired boilers, the cost of using coal-fired boilers and gas-fired boilers are different from each other. Comparing the operating costs of 4 tons of natural gas boilers and 4 tons of coal-fired boilers, we must first understand the 4 tons of natural gas boilers and 4 tons of fuel Specific parameters of coal boiler:


1. Technical parameters of 4 tons natural gas boiler:

4 tons natural gas boiler

Model specification: WNS4-1.25-Y(Q)

Rated evaporation: 4 t / h

Rated working pressure: 1.25 MPa

Feed water temperature: 20 ℃

Outlet steam temperature: 194 ℃

Hydraulic test: 1.65 MPa

Boiler water capacity: 8.5 m3

Cold air temperature: 20 ℃

Smoke exhaust temperature: 80.7 ℃

Boiler design efficiency: 94.8%



2. Technical parameters of 4 ton coal fired boiler:


4 ton coal fired boiler



Model specification: DZL4-1.25-AⅡ

Rated evaporation: 4 t / h

Rated steam pressure: 1.25 MPa

Rated steam temperature: 194 ℃

Feed water temperature: 20 ℃

Design fuel: molded biomass pellets

Factory mode: quick install




3. Operating costs of 4 tons of natural gas boilers and 4 tons of coal-fired boilers

Because the calorific value of coal is about 5500Kcal / Kg (calculated according to standard coal), the market price is 800 yuan / ton, the coal consumption per ton of steam is 0.2 tons, and the price is 160 yuan / ton of steam; The price of natural gas is 3.3 yuan / m3, the heat generated by 0.2 tons of coal is equivalent to 46.05m3 of gas consumption, and the price is 151.96 yuan / ton of steam. Based on the annual production of 2000 hours, 4T steam boilers use natural gas annually to save RMB 154,000 compared with coal.


It can be seen that the 4-ton natural gas boiler not only has a low operating cost, but the 10-ton gas-fired boiler can greatly improve the working environment, reduce the labor intensity, and improve the enterprise’s taste. The operating cost of a 4 ton natural gas boiler still has a large space to fall compared with coal-fired boilers.
