Vietnam Packaging Factory 8,000 kgs/hr, 20bar steam boiler

Question:

Hi Sir,

Do you supply boiler with 8,000 kgs/hr, 20bar steam pressure? fed with gas

We will use it for packing company in Vietnam

Can you send us your proposal ?

Thanks

ZBG Engineer Li Answered:

ZBG can provide 8 tons of steam boilers with various fuels, such as 8 tons of chain grate steam boilers, 8 tons of oil and gas steam boilers, 8 tons of coal-fired steam boilers, 8 tons of biomass steam boilers, etc. It can be used in packaging factories, but also in feed factories, chemical factories, clothing factories, food factories, beverage factories and so on.

Taking an 8 ton boiler as an example, what is the fuel cost of an 8-ton gas-fired boiler and a coal fired boiler?

The gas consumption cost of an 8-ton gas-fired boiler can be calculated first by calculating the gas consumption of its 8T gas-fired boiler, and then multiplied by the local gas price based on the gas consumption.

The calculation formula of gas consumption of gas boiler is: gas consumption of gas boiler in 1 hour = gas boiler power * 3600s/fuel calorific value/thermal efficiency.

It is known that the power of an 8-ton gas boiler is 5.6MW, and the calorific value of natural gas is 38MJ/M3. The thermal efficiency of the gas boiler produced by Zhengzhou Boiler can reach 92%, then =5.6MW*3600s/38MJ/92%=577Nm3

If natural gas is 3.8 RMB/Nm3, then the gas consumption cost of an 8-ton gas-fired boiler = 577Nm3*3.8 RMB/Nm3=2192.6 RMB

8 tons chain grate steam boilers

The same as the natural gas calculation formula, the heating power of an 8-ton coal-fired boiler is 5.6MW, the calorific value of bituminous coal is generally 22.3MJ/kg, and the thermal efficiency of an 8-ton coal-fired boiler is about 80%. The formula: 5.6MW* 3600/22.3MJ/80%=1130KG. If calculated at 800 RMB per ton,

The fuel cost of an 8-ton coal-fired boiler=1130KG*0.8=904 RMB

If you compare the fuel alone, coal-fired boilers definitely have an advantage over any kind of fuel. However, gas-fired boilers are better than coal-fired boilers in terms of environmental protection. If you need us to make a plan, please consult our online customer service!
