At present, in the domestic boiler industry in China, due to the presence of S in fuels such as coal, oil, and natural gas, SO2 and SO3 are usually produced during combustion. SO2 and SO3 combine with H2O to form sulfurous acid or sulfuric acid vapor. When the temperature of the metal wall of the heating surface at the tail of the boiler is lower than the condensation point of sulfuric acid vapor (called the acid dew point), liquid sulfuric acid will form on its surface (called condensation). For a long time, corrosion of the tail heating surface of air preheaters caused by condensation has occurred frequently and is difficult to avoid. So much so that currently in boiler design, it is necessary to alleviate the occurrence of condensation and corrosion by increasing the exhaust gas temperature or using non-metallic materials with extremely poor heat transfer (such as enamel pipes), without fundamentally solving the problem. Simply increasing the exhaust temperature will inevitably result in a large amount of low-temperature energy
Boiler blowdown can control the salt content of boiler water, but it causes loss of working fluid and heat, so the amount of boiler blowdown should be limited. The amount of boiler blowdown is usually expressed by the blowdown rate P The pollution discharge rate is the percentage of the amount of pollution discharged to the boiler's evaporation capacity According to the "Regulations on Electric Power Technology Management (Trial)", the emission rate of condensing power plants is 1% to 2%, and the emission rate of thermal power plants is 2% to 5%
The thermal efficiency of a silicon crystal tube refers to the proportion of the energy released after heating the tube to the entire heating product per unit time and per unit product. 1、 Characteristics of silicon crystal tubes: 1. The physical properties of silicon crystal tubes are very stable, with high mechanical strength, good seismic performance, and are not affected by external temperature changes; 2. Silicon crystal tube is resistant to acid and alkali, not affected by chemical corrosion, and has good corrosion resistance; 3. Silicon crystal tubes have characteristics such as high thermal conductivity, good sealing performance, and large resistance to thermal disconnection; 4. Silicon crystal tubes have advantages such as strong insulation resistance, environmental friendliness, and energy saving; 5. Compact structure, low thermal resistance, and small shrinkage coefficient at ordinary temperatures;
Zero leakage vacuum thermal energy recovery device technology and working principle: The zero leakage vacuum thermal energy recovery device is a new type of heat transfer element, which should be called a "closed two-phase heat transfer system" according to a more precise definition. It is a device that relies on the phase change of the fluid inside (liquid to vapor and vapor to liquid) to transfer heat in a closed system that has been evacuated. In recent years, zero leakage vacuum thermal energy recovery device technology has developed rapidly. Due to its advantages of fast heat transfer speed, high thermal efficiency, and low operation and maintenance costs, it has been widely used in various fields of waste heat recovery.
In the fields of petrochemicals, printing, artificial leather and electronic components, baking paint, and pharmaceuticals, volatile organic compounds (VOCs) are commonly used as solvents. If these organic solvents evaporate into the atmospheric environment, they will not only cause serious pollution to the atmosphere, but also pose a threat to human health after inhaling polluted gases.
Calcination furnace is a type of equipment used for high-temperature treatment, using natural gas, oil, and electricity as energy sources, for ironmaking, rare metal recovery, catalyst production, environmental improvement, and production of specialty chemicals. The calcination furnace uses direct or indirect heat sources and can continuously process batches of materials at medium and high temperatures, ensuring the isolation of heat sources and products during the processing. In industrial production (such as catalyst production, hydrocarbon processing, chemical production), the insulation of the calcination furnace is very important and has great value.
A direct fired furnace consists of three parts: a combustion system, a flue gas system, and a control system: 1. The combustion system consists of a burner, a combustion air system, a gas supply system, and an ignition system. A burner: Two burners are set up in a staggered arrangement in the flue gas duct to facilitate uniform mixing of heated flue gas (facilitating uniform thermal expansion of the flue gas duct and uniform inlet temperature of SCR); B Combustion air system: Under normal circumstances, flue gas is used as the combustion air, and in the event of a fault, it switches to air combustion; C ignition system: using plasma ignition; Shichu 2. The flue gas system consists of a flue gas diversion device, a combustion chamber, and a mixing chamber. The flue gas is divided into three streams by the diversion device, and the two streams on both sides flow through the combustion chamber from the outside for preheating. Afterwards, the smoke in the middle, as well as the high-temperature smoke generated by combustion
