Apply incinerator 9 big attention incident
Note the following when using incinerators:
1.When the gas incinerator produces secondary combustion failure one after another, it shall stop the machine and check whether the gas supply system of the incinerator is normal and whether the circuit connection is accurate. After removing obstacles, the incinerator can be restarted.
2.It is strictly forbidden to use wrench or metal rod to knock or conflict the gas supply pipeline, which will avoid causing static electricity or spark and stimulate the gas explosion.
3.Smoking, welding, cutting and other illegal work are strictly prohibited in the air supply valve set or the flange face of the pipeline.
4.It is strictly forbidden to hold any open fire attempt next to the pipeline and valve group and pressure regulating valve.
5.Try whether there is fuel in the air supply pipeline, usually try with the gas low-pressure meter.
6.In the air supply pipeline, that is, after the discharge, but there are residual gas or liquid droplets on the wall, such as electrostatic spark and open fire will cause burning and explosion.
7.When the air supply pipeline has been aerated, and the valve set is obstructed when the demand is destroyed, the front end of the valve set must be cut off at the beginning, and then the gas in the pipeline from the main valve to the valve set should be emptied, and then the damage and after-sales of the valve set can be carried out.
8.In debugging, gas must be serious, safe and efficient.
9.No explosion-proof electric power opening tools are allowed to be used on site.

In many projects, after the growth of smoke outside the cycle, according to the feedback on the site, smoke re cycle condensate water a lot, in winter, the wind tunnel and even ice.This is due to the dry and cold flue gas and combustion fresh air inclusion, mixed with the steam than the inclusion of wind temperature saturated humidity, excess water vapor caused condensation.CO2 in the flue gas will dissolve in condensed water, acid condensed water if it comes in the incinerator fan, easy to corrode the incinerator or fan components.Is to be adopted to prevent condensation water coming in the incinerator or fan.Add insulation to the reincarnated smoke pipe, reserved condensate water outlet, fresh air and preheating.
In the cycle of the flue at a very low point configuration condensation water discharge assembly, such as mixing bellows, should also be configured on the mixing bellows condensation water discharge assembly, when necessary, can also be configured on the fan condensation water discharge assembly.The condensed water discharge assembly is made of water seal type, the water seal is very high lower than the flue gas pipe is very low, which is convenient for condensate water to squeeze out.
EBICO supplies light and heavy oil pump units with filters, pumps and heaters (heavy oil), filters with oil pump admission or two-way one-stand-one-use plan.The acceptance of a two-way system ensures that the system does not need to be obstructed by normal inspection or discovery of obstructions.Heavy oil can be heated by electricity, heat conduction oil and steam ring to reach the viscosity required for atomization.
EBICO supplies safe light and heavy oil models with matching valve sets, fuel required for incinerator quick and active cutting valve, atomizing ring quick and active cutting valve, pressure master, pressure gauge and temperature gauge (heavy oil only), modular plan for quick and easy placement.
From the perspective of heat exchange calculation, it is necessary to increase the heat exchange surface, improve the heat exchange compliance of the heating surface, improve the heat exchange temperature difference of the cooling source at a lower temperature, and reduce the influence of corrosion on the heat control compliance.As gas steam kettle host start burning furnace volume and content low nitrogen flame size request, the second host of convection heating surface is a main export to low smoke temperature, average in 150 ~ 250 ° C, in order to survive the smoke temperature is too high growth together with the difficulty of flue heat preservation plan, smoke temperature is too low will cause wall condensation in furnace convection heating surface lead to corrosion, therefore, proper heating furnace domestic demand plan, the physical dimension more representative chamber size.To increase the heat exchange surface, it is important to think about increasing the heat exchange area of the building at the end of the boiler, which is more beneficial to the rapidly lowering smoke exhaust temperature.Second, the lower inlet water temperature can be used for heat exchange temperature difference characteristics;Third, it can accept the construction of corrosion-resistant materials and improve its service life.The new layout of efficient heat exchange must adopt the modes of staggered tube arrangement, efficient heat exchange finned tube and plate heat exchanger, increase the smoke disturbance and battle surface, reduce the smoke stratified heat resistance, advance medium and smoke heat exchange compliance.
