Low NOx light oil fired hot water boilers dealer with CE
Fangkuai boiler manufacturers tell you the importance of leakage protection-leakage protection is automatically cut off the power supply; overheating protection that is, when the boiler water temperature reaches the alarm temperature, automatically stop the burner and send an alarm; The secondary superheat protection means that when the boiler shell temperature exceeds 105 ℃, the operation of the Fangkuai boiler factory automatically cuts off the secondary loop and the boiler stops working. When the water level of the boiler is reached because of other reasons, when the water level is lower than the very low water level, the boiler will stop working and prevent the danger of dry burning. All-in-one insulation using glass cotton, Light weight, good heat preservation effect, less heat loss. White color board packaging, beautiful and generous, sealing good corrosion resistance, mechatronics, small space, easy to use. Gas-fired boilers are widely used in supermarkets, hospitals, schools, guesthouses, residential areas, bath centers, etc., fully automatic heating for users or provide bath water, domestic hot water.

Gas-fired boiler 2, equipped with imported brand burners, high degree of automation, automatic purge according to controller instructions, electronic automatic ignition, automatic combustion, air, oil (gas) automatic proportional regulation, safe and stable performance, good combustion effect. And there is a extinguishing protection device to ensure the safe operation. 3, the fire pipe is inserted with flame retardant spoiler, slow down the smoke exhaust speed, strengthen heat transfer, smoke temperature from the smoke chamber is low, reduce heat loss, save fuel. 4, large font shows the water temperature, It is convenient to master the operation of the boiler and the system. The water temperature can be set at random from 10 ℃ to 90 ℃, and the boiler is fully automatic heating to the system or for Users provide life, bath with hot water.
"Thalia T6" is a fast-party R & D team after more than 600 burn test, 30 times optimization technology, successfully developed the premix vacuum low nox fired hot water boilers dealer with ce. Professional designers based on product characteristics and application environment painstaking design, look as elegant as the goddess of wisdom, asymmetrical waistline but also demonstrates its different. Internal boiler U-tube smoke fast original square, weld-free bending forming, in combination with a compact furnace; no need to provide special transfer smoke chamber, the smoke box integrated with the condenser, thereby reducing the space occupied area, compared with the generation volume reduced by 33%.
The wns series of oil and gas boilers produced by ZG boiler have realized full automation operation, equipped with burners with good self-control performance, high degree of automation, automatic conversion from pre-purge, ignition, automatic ignition to automatic shutdown and flameout protection. control. The boiler's water supply, combustion and other thermal process variables can also be automatically adjusted to achieve automatic water supply. In terms of pressure control, the pressure display and control automation in boiler operation are realized. In terms of water level control, the wns series oil and gas boilers realize the water level display and automatic control functions in boiler operation. This ensures safe operation of the boiler from all aspects while reducing labor costs.
Solutions and prevention of gas oil-fired boiler flameout Today we'll resolve what about gas fuel boiler flameout solutions and prevention fuel gas-fired boiler flameout Solution: First, the furnace pressure gauge indicates the value suddenly increases, the furnace black can not see the flame, burning furnace sounds disappear, extinguishing the flame supervision devices emit a signal; the temperature dropped sharply atmospheric pressure, the water level dropped after the first rise, and so are flameout phenomenon. Auxiliary flame caused by an accident, such as a fan, blower power interruption, there is an accident signal emitted; fuel supply as a result of intermittent, the boiler is oil or gas pressure drops to zero, only a single burner flame, the furnace may also be thrown skew central flame extinguished burner pressure change; as a result of the fuel supply interruption, the extinguished burner pressure or hydraulic indication may drop to zero, and the fuel consumption, the gas pressure is increased other operating burner. Causes gas boiler flameout are: sudden increase in gas pressure caused from the fire, the solenoid valve malfunction the gas supply interruption, the gas composition has changed so much moisture content is too high and so on. Blower, fan failure, the load is too low furnace pressure is too large excessive leakage and other excessive wind, so that the furnace temperature is too low can also cause the boiler flame. Cause misfire has oil-fired boiler: oil pump failure, the oil surface is exposed inhalation tube, clogging of the oil filter or oil supply pipe, a solenoid valve malfunction or misoperation caused by oil running intermittently. During transport the fuel with steam by heating water; inappropriate position inhalation tube with the pumping of water; improper contaminated oil floating on the water; poor dewatering tank drain plug such that the fuel with water. After the explosion should be taken to prevent the furnace boiler flameout, it must immediately cut off the fuel supply to the furnace, and then block the electromagnetic valve of the gas supply valve to seal off the fuel supply to run the burner. When the action to be fast in order to avoid inheritance or restore fuel supply during operation, causing the furnace explosion. And identify the cause of boiler flameout troubleshooting find a good job and then start the preparatory work. Before starting the boiler should be enhanced ventilation purge, purge time is more than 5min, then procedures ignition. It is forbidden to send fuel directly to the high-temperature furnace without using an ignition spark ignition device to prevent furnace explosions. If due to fan failure caused when the flame should be quickly cordoned off the fuel supply line of each valve, with special attention because the valve is not tight blockade caused by leaking fuel. Ventilation and purging of the furnace and flue in accordance with the approach of an emergency shutdown. Ignition step by step in the recovery operation after the fan. Single burner flame burner only block the fuel supply valve, the burner off a small damper identifying and troubleshooting and then re-ignition by the ignition process. Boiler flameout of prevention: For oil-fired boiler should minimize the possibility of fuel transport, storage and handling of water in all sectors. Tank initiative measures should dehydration and dehydration on schedule. In any case, it should ensure the security of oil supply. The supply of oil and acceptance testing, cutting oil change when the master species. When a large change in oil types, varieties and the need for the oil tank to store the original varieties contaminated test to determine whether the same storage tank, to prevent the density and viscosity differences between a large number of decomposed oil mixed insoluble material, clogging oil pipeline. For the operation of the gas boiler should be closely monitoring the evolution of gas pressure, the timely processing of exceptions thrown up air pressure, ensure the supply pressure in the normal range. To always understand, repair gas composition, gas composition changes when large, to take the necessary adjustment measures on the boiler operation.
