If you know a little about chemistry, you may know that the sulfur content of oil and coal is roughly equal, but ask what low-temperature corrosion of oil-fired boilers is much more serious than coal-fired boilers, for two main reasons:

1. 90% of ash in coal-fired boiler, especially coal powder furnace, is taken away by flue gas, sulphuric acid steam formed in flue gas is absorbed by fly ash in flue gas, so that sulfuric acid vapor in flue gas is reduced, and about half of sulfur remains in ash when coal is burned. When the oil is burning, the sulfur content in the fuel almost all changes to the ash in the SO2, fuel, the fly ash in the flue gas is very little, and the adsorption ability to the sulphuric acid vapor in the flue gas is very weak.

2. The hydrogen content of oil in the oil-fired boiler is about 11%-12%. The combustion of each ton of fuel oil can produce about 1 ton of water vapor, and the partial pressure of steam in the flue gas is higher than that in the case of coal-burning.

4 tons of 5 tons steam boiler in brewery before firing what needs to be done to prepare a deal boiler conduct a comprehensive inspection before Sheung Shui, the water is softened before boiler water filling. 2, Sheung Shui should check whether there is water leakage valve, leaks should be immediately removed when found. 3, the check Sheung water temperature, pressure gauges, water level, no good production of inlet and outlet valves, smoke profile, said shutter is flexible, the flue gas channel is smooth duct, each cleaning doors are tight. 4, before firing coal with water 8-10%.

Basics gas and steam oven basic principle as the principle gas 5 tons steam boiler in brewery and knowledge: steam as a heat carrier gas, forced circulation pump circulating the liquid phase, and then reheated to return, once-special industrial furnace. Widely used, such as petrochemicals, textiles, printing, plastics, rubber, food processing, wood processing, thermal asphalt, carton production, vegetable dehydration, drying, and other drying foundry sand. Gas steam boiler is an energy, security, heating equipment, is an ideal alternative to steam boiler products. The working principle is conveyed back to the respective thermal heating apparatus petroleum oil heater (endothermic) (organic heat), heat conduction through the (thermal energy release), and then returned to the furnace, formation of a closed circle in the process of compulsory to achieve the purpose of heating. Performance and features: 1, low temperature. As the temperature rises conductive oil, the viscosity of the system will continue to reduce resistance to decline, it will also reduce stress, more conducive to the safe operation and safe operation. Steam boiler is high pressure high temperature plume. 2, gas and steam heating system uses hot water inlet and outlet temperatures and equipment is 20-30 degrees, the closed forced circulation, heat recovery can be repeated, there is no waste, high thermal efficiency, energy-saving effect. 3, a low pressure gas and steam heating system, requires pressure equipment and the system will be reduced, and therefore, a simple production process of steam boilers, low investment costs. 4, the thermal efficiency can be maintained at optimal levels in various loads a level of 320 degrees and can adapt to the production requirements of the following types of thermal load, and temperature control can be precisely adjusted. 5, heating furnace to increase two to three times the temperature cycle can provide a wide range of processes, a variety of equipment to meet the different temperatures greatly reduces the need for investment in equipment.

Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type boiler paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing 5 tons steam boiler in brewery for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.
