Before purchasing a set of oil-fired boiler, users should not only care about the quality and price of the boiler, but also consider the thermal efficiency and operating cost of the boiler. Oil-fired boiler is a kind of large-scale industrial equipment, and its energy-saving effect determines the operating cost of a ton of oil-fired boiler, so enterprises should pay attention to it.
Generally speaking, the operating cost of one ton oil-fired boiler mainly includes fuel cost, electricity cost, w...
When it refers to how to reduce the procurement cost of industrial boilers, many corporate users will be first to take measures to effectively reduce the related costs involved in the boiler procurement process, such as the boiler equipment cost, transportation cost, loading and unloading cost, insurance cost, installation and commissioning cost, labor cost, acceptance and inspection cost.
The coal-fired boiler has low fuel costs and high calorific value, which is a kind of important auxiliary heating equipment in the production-oriented enterprises. However, the coking on the furnace wall is common in the operation of the coal-fired boiler.
Regular inspections can identify and correct faults in the safety systems that are designed to prevent accidents.
When it comes to regular maintenance, the cost of the inspections and repairs will be dramatically lower than the loss of time and profit from a broken boiler that requires replacing. Don’t let maintenance fall by the wayside. Schedule it at even intervals throughout the year.
1. They are all a heat conversion device. The heat transfer medium they use is different. The water used in the steam boiler is heated to become steam. The heat transfer medium of thermal oil heater is heat medium oil. The heat is transferred to the heated substance by the heat medium oil.2. When a higher heating temperature is required, such as 280 degrees, the steam pressure of the steam boiler should reach 7MPa or more, and the process piping and heat exchange equipment must also withstand the same pressure. The equipment cost is high and dangerous. Thermal oil heater provides a temperature above 280 degrees, but the pressure is lower than 1MPa.3. The temperature of thermal oil heater can be accurately controlled within 3 degrees and the temperature of the steam changes greatly.4. Thermal oil heater is used alone, the exhaust gas temperature is higher, and the thermal efficiency is lower than that of the steam boiler. However, if used in conjunction with a steam boiler, the
(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):Biomass environmental protection and energy saving fuel made of straw and livestock etc., their combustion is not full. Answer: The cause of the problem:1. Air quantity is insufficient or too big.2. Outer flame position is not proper.Troubleshooting:1.Sufficient temperature： sufficient combustion of biomass boiler needs high temperature, combustion rate is proportional to the temperature, to raise the temperature as much as possible but guarantee there is no slagging.2. Proper air volume. If the air volume is too large, it will reduce the temperature of the furnace and increase the incomplete combustion of fuel. If the air volume is insufficient, the combustion efficiency will be reduced, and the waste of fuel will also increase the emission of smoke.3. Sufficient mixing of fuel and air. During the burning stage of biomass boilers, the sufficient mixing of air and fuel should be ensured and the disturbance should be strengthened during the burnin
