A firetube boiler can react very quickly to load changes due to the fact that it has a large volume of stored energy in the form of hot water and steam.
The pharmaceutical sector is an area that requires the highest quality steam for its processes, known as clean steam, instead of other industrial steams. Some processes in this sector even need the highest level of quality - pure steam, which involves even stricter steam purity requirements for use in the sterilization of raw materials and pharmaceutical products at high temperatures.
Selecting a gas-fired boiler for heating a 200,000 m^2 area involves several considerations to ensure efficient, reliable, and cost-effective operation. Here’s a structured approach:
1. Determine Heating Demand
First, calculate the total heating demand of the 200,000 m^2 area. Heating demand varies based on climate, building insulation, usage, and local standards. A rough estimate for moderate climates is 100 W/m^2, but this can vary.
2. Choose Boiler Type
Decide on the boiler type. Fo...
Combustion Efficiency
Combustion efficiency is the effectiveness of the burner only and relates to its ability to completely burn the fuel. The boiler has little bearing on combustion efficiency. A well-designed burner will operate with as little as 15% to 20% excess air, while converting all combustibles in the fuel to thermal energy.
Thermal Efficiency
Thermal efficiency is the effectiveness of the heat transfer in a boiler. It does not take into account boiler radiation and convection losses - for example, from the boiler shell, water column piping, etc.
Fuel-to-Steam Efficiency
After combustion, biomass-fired boiler fuel will generate energy and also produce some combustible matter in fly ash which will have bad influence on the surrounding environment. Therefore, in order to realize the goal of environmental protection, we should reduce the generation of combustible matter in fly ash in biomass-fired boiler fuel.
The air oxygen content's effect on the boiler is mainly reflected by the effect on the blowing rate. Boiler will have typical phenomena if the blowing rate is high or low.
