| Same operating conditions | Fossil fuels, coal, firewood, biomass and biomass | Liquid fuel, gas |
|---|---|---|
| Installation area | The Boiler system is composed of many equipment that need a large installation area, need more space for fuel storage, waste treatment system, etc. | The boiler system is compact in structure, does not need space for fuel storage, waste treatment system, etc. |
| Environment | - Generate dust during transportation and unloading. - When operating a large exhaust smoke derivative, the smoke component index is high. | - Working environment, clean and friendly - When operating, exhaust fumes always meet the criteria of QCMT, the index of smoke gas components is low and completely absent. |
| Operate | -Need an operator when operating and handling because there are many devices operating independently. - For large systems, 4-5 people are needed in 1 shift, and for small systems, about 1-2 people in 1 shift. | The furnace is designed to operate automatically, independent of the operator. |
| Maintenance, cleaning, repair | - Complex system, high cleaning cost. - Need to clean weekly, monthly. - Long and complicated editing time. | -Simple system, easy to clean. -No need for continuous cleaning, can be up to every 6 months. - Quick and simple repair and replacement time |
| Longevity | - Equipment has a lifespan of 10-20 years depending on the manufacturer. Internal components need to be replaced in order to function. - The fuel feeder is usually 3-5 years old after the warranty will be damaged, due to the friction of the solid material. - Auxiliary equipment, water heater, air dryer has a lifespan of about 4-5 years and must be replaced - Dust filter cyclone system is also worn by friction and has a lifespan of 5-6 years - Old water dust suppression treatment system Lifetime, when the warranty period expires, is about 1-2 years like the pump system. - The pipeline system is the same, it takes about 2-3 years to replace. | -Equipment has a long life, can be up to 50-60 years. |
| Electricity | -High and very high power consumption. Because many electrical appliances have very large capacity, such as fan system, feed system, smoke treatment system... - Due to the humid and dusty environment, the lifespan of electrical appliances is reduced. | - Energy saving during use. -The electrical system is also very durable to use |
| Country | -Requires a lot more water - To cool down as well as clean solid waste, furnace surface. - In addition, the water must also be treated for the exhaust fumes of the boiler. | - Do not use much water |
| Waste Treatment | -Need to treat the ash of combustion products -Need to treat the sludge of the smoke treatment system -Need to treat the water of the smoke treatment system | Not available |
| Construction and installation time | -Longer fabrication time -Longer installation time -More dangerous construction and installation because the furnace is usually very large and very tall. | -Fast fabrication time -Fast installation time -Simple construction with low hazards |
| Price | -High cost due to the heating of the furnace body, in addition, there are many accompanying equipment. Including water heater, air dryer, fuel supply, exhaust gas treatment system... - More construction workers | - Cheaper cost due to simple structure. - Few construction workers. |
| Fuel price | -Use low-grade fuel with small calorific value, so the unit price is cheaper. | Using fuel with high calorific value, the cost is also higher. |
