high quality horizontal gas steam boiler

Condensing a portion of the air preheater and use of double combination economizer design. Internal economizer heat exchanger elements using the new technology - the wings of the tube instead of finned tubes, a five-fold increase in heat transfer area at the same volume, latent heat of vaporization of the portion of the flue gas is sufficiently absorbed, effective utilization of the fuel energy, energy saving at the same time enhance the efficiency of the use of the boiler. Air preheater is further absorbed by the air and the flue gas convection heat latent heat of flue gas, and the air heated by the air preheater is connected directly into the burner tube, providing warm air for the fuel, thus improving combustion efficiency. This exhibition brings Chinese fast "Euromonitor" series boilers attracted a large number of customers, to give customers unlimited. Here, fast Boiler staff wish the exhibition every success.

Steam boiler must be shut down? For gas-fired boiler will be some companies: the higher cost of oil-fired boilers and electric heating boilers, many SMEs simply can not afford, the thermal efficiency of the boiler is too low, gas consumption often can not keep up. Many reasons why gas boiler known as the preferred place of the main gas boiler. In business consulting to some customers learned, after being forced to shut down the gas boiler, no steam, the company has only discontinued. In order to survive companies only replace the boiler, to select the gas-fired, oil-fired boiler, electric heating boiler and a biomass pellet boiler. Currently the market for natural gas boilers only major selection, analysis of the reasons is that gas-fired gas boiler is fully automatic, with no pollution. But in reality, many businesses faced to replace the boiler, gas pipeline did not pull in place, some companies simply do not have natural gas pipeline, high quality horizontal steam boiler must be shut down? Gas boiler gas boiler, not to mention the natural ventilation. This is the biggest obstacle currently facing.

Steam boiler When should an emergency shutdown when the high quality horizontal steam boiler Shanghai encountered the following situations, gas boiler manufacturers need to take emergency shutdown measures: (1) When the steam boiler water level gauge water level drops below the lowest water level, through the "call water when the "law also failed to see the water level. (2) increase the boiler when the water level continued to decline up time. (3) water supply system failure, unable to supply water when the boiler. (4) water level gauge and a safety valve failure, can not guarantee the safe operation of the boiler. (5) When the control valve and the drain valve malfunction when closed lax. (6) when the pressure receiving surface of the waterwall tubes or boiler smoke tubes bulging or cracking occurs, the furnace wall, collapsed down occurs when the front arch. (7) In case of failure of a safety valve, pressure gauge displays the boiler overpressure operation. When by the above situation, should immediately shutdown, should turn off the blowers, the door opened quickly, quick rotation of the grate, the furnace temperature is lowered to withdraw the fire, the coal supply is stopped. When the boiler overpressure, open the emergency vent valve provided on the sub-cylinder is discharged down. When the furnace severe water shortage, should not panic, in order to avoid operational errors. At this time, non-watered furnace. Then reduce oven temperature to find the reasons to be processed.

What are the precautions in the loading and installation of gas-fired high quality horizontal steam boilers?

Gas-fired steam boilers are a very wide range of special equipments, widely used in food, chemical, paper, textile, construction and other industries. In the process of loading and installing a gas steam boiler, some problems must be paid attention, otherwise it may cause a certain degree of economic loss.

1. Pay attention to the following matters during the loading and unloading and handling of gas-fired boilers: the lifting capacity of the lifting equipment should match the weight of the lifting boiler. The lifting lug on the boiler with the lifting lugs that cannot be used for lifting can not be used for lifting. The length of the steel cord should be reasonably selected to avoid the scratching of the furnace due to the improper length of the steel cord. The boiler must be protected from any damage during handling and handling.

2. Reserves for maintenance space When installing boilers, ensure that there is sufficient maintenance space around the boiler.

3. Setting and precautions for the base and base of the gas steam boiler The boiler body must be installed on the basis of 100-150mm above the floor of the boiler room. It must be confirmed with the technical personnel of the boiler manufacturing company in advance and constructed according to the basic drawings. The anchor bolts must be reserved on the foundation. The foundation shall be capable of withstanding the maximum weight of the boiler and the amount of water it holds. When installing the base, you must first position it. After positioning, adjust to the same length of the two diagonals of the base, and then tighten all the fixing bolts. The installation of the base is carried out with reference to the reference line.

4, general precautions Be careful not to tilt and impact the boiler and accessories too much. No combustibles can be placed around the boiler. Do not use oil and water to smother the boiler. The boiler should normally be installed in a separate boiler room. The new gas-fired boiler room should not be connected to the house. The boiler room shall not be connected to Class A, Class B and Category C fire hazard rooms using flammable liquids. If connected to other production plants, the application firewall is separated.

5. The fire resistance grade and fire protection requirements of the boiler house building shall comply with the requirements of the Code for Fire Protection of Building Design and the Code for Fire Protection Design of High-rise Civil Buildings. The ground of the gas steam boiler room should be flat, non-flammable, no water accumulation, and the foundation load should meet the requirements. The power supply voltage of the gas steam boiler room should be stable to avoid causing the electrical components to burn out. If the voltage is unstable, it is recommended to install a voltage regulator. Ventilation equipment should be installed in the boiler room, and the boiler should be kept at room temperature below 50 °.
