“gas and oil boiler”- related faq

For the selection of heat fluid boilers, first step is to determine several parameters: thermal power in the process, the oil temperature, and the use of waste heat.There are several methods for determining the boiler's thermal power:1. Calculation. According to the specific heat capacity of the material to be heated, the heating temperature difference, the processing amount per unit time, etc., the thermal power is equal to the product of the above three points, and the calculation result considers a certain margin amount as the boiler capacity.2. The sum of thermal power in the process equipment can also be used as the basis for the heat power.3. Refer to the experience of the same industry to increase or decrease on the basis of peers.4. If steam heating is used, it can be converted into heat transfer oil of the same tonnage and the capacity is appropriately reduced.The determination of the temperature of the heat transfer oil can be determined according to the characteristics of th

The life of the heat medium oil for thermal oil heater is related to the operating temperature, and the life is shorter when the operating temperature is high.After half a year, the heat medium oil is used for sampling every 2-3 months. When the flash point of the heat medium oil changes by more than 20%, the acid value is less than 0.5 mgKOH/g, and the residual carbon is less than 1.5 wo/o, when the color of oil becomes dark, it indicates that it has failed and needed to be replaced.The relationship between heat transfer oil life and temperature is shown in the following table: (unit, year)  360℃ 360℃      360℃   360℃ 360℃   Neo SK-OIL 1400  10 Neo SK-OIL 1400  10 Neo SK-OIL 1400  =1 3-4 8-10 >10 KSK-OIL 280  1 3-4 6-8 >10

Chemical industry: polymerization, condensation, distillation, rectification, concentration, evaporation, and melting.Petrochemical: synthesis, reaction, distillation, rectification, heating, heat preservation, storage tank heating, heavy oil heating.Oil grease: oil decomposition, deodorization, fatty acid distillation, heating, hydrogenation reaction, esterification.Plastic rubber: hot pressing, calendering, extrusion, vulcanization molding.Leather industry: artificial leather processing.Textile printing and dyeing: heat setting, drying, baking, evaporation, melting.Chemical fiber: polymerization, melt spinning, weaving machine processing, molding, thermosetting, stretching, drying.Paint: paint baking, drying, high temperature solid melting, home appliances, vehicle baking paint, painting.Automotive aircraft: painted baking, drying, thermoforming, high temperature bonding.Wood processing: hot pressing, drying, wood processing and wood products (materials, furniture), wood-based panels

Specific performance:Low level alarm of expansion tank.Answer：Cause of failure:The pipeline system (including heater) has not been replenished in time after oil leakage or degassing. Troubleshooting:Eliminate system defects and add oil.

(Question details) Specific performance:The temperature difference between the inlet oil and the outlet oil temperature of the boiler exceeds the given value.Answer：Cause of failure:(1) The oil supply of the heat oil circulating pump is insufficient.(2) The boiler operates overload.(3) Thermal oil metamorphism.(4) The boiler does not match the heating equipment.(5) Bad insulation effect.(6) There is gas or steam in the thermal oil. Troubleshooting:(1) Remove the faults of oil pump and pipeline.(2) Operate at normal load.(3) Change new oil.(4) Choose proper boiler.(5) Check the insulation layer and repair the loopholes.(6) Remove air or steam. ZOZEN pays much attention to boiler furnace insulation also, the inside is made of high quality insulation material, external use of stainless steel plate, which can maximumly reduce heat loss and improve the operating environment.

(Question details) Specific performance:There is hammer sound in the oil inlet pipe, and the pointer of the inlet and outlet pressure gauge fluctuates.Answers: Cause of failure:The system contains gas and moisture.Troubleshooting:(1) Exhaust air.(2) Cook oil.
