What are the precautions in the loading and installation of gas-fired 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 °.

The boiler application requires a boiler body and many boiler fittings are required to form a complete system. The oil and gas boiler fuel system mainly provides fuel for the boiler, and has the functions of fuel receiving, storage and transportation. The combustion system mainly includes a burner and a matching valve instrument. The choice of burners is cautious, the characteristics of the fuel, and the boiler flue gas emission standards have a large impact on the choice of the burner. Oil and gas boiler flue gas systems generally require more configuration of induced draft fan, flue gas purification (dust removal, desulfurization, denitrification) equipment, chimneys and other equipment. The soda system requires many accessories to assist, including steam (hot water) equipment, water supply equipment, sewage equipment, and so on. The electric control system of ZG boiler oil and gas boiler is responsible for the safe operation of the boiler body and all auxiliary machines. Its function is to automatically detect, program control, automatic protection and automatic adjustment of the operating boiler. Instrumentation and automatic control equipment include thermometers, pressure gauges, water gauges, flow meters, negative pressure gauges, oxygen meters, automatic regulating valves, microcomputers and automatic control systems.

Recently, in Qinghai Province Jigzhi County Market Authority carried out a special inspection of boiler safety within the county, mainly in order to further strengthen the special equipment safety supervision, investigation and potential risks.

County Market Authority was held on June 8 special meeting to make arrangements for this special inspection work; the meeting, Secretary of this special inspections put forward specific requirements: Either the county government and relevant departments in accordance with the superior, all in the area to check boilers, boiler and disabled to look back, to verify the implementation of the rectification; the second is to designate a person to carry out checks to ensure that this special inspection into effect, produce results; the third is to check violations found to be severely dealt with according to law.

Subsequently, according to the spirit of the meeting, Jigzhi County Market Authority Board redoubling its efforts to carry out special inspections. 5 out of law enforcement officers were examined using 10 units. The county has been reported to stop the boiler After registering with and eleven inspection and verification. Focus on checking whether the boiler inspection, whether the registration, check whether safety accessories in place, whether fireman certificates and other issues, focusing on correct pressure boilers, waste heat and pressure tanks and other equipment as well as the use of pressure boiler overpressure operation and other illegal operations behavior, found hidden among all checks for disposal in accordance with law, to ensure the safe operation of the boiler county.

Next, the county will further increase the pressure in the boiler with supervision and do routine inspections and safety management, strengthen the use of units to pay a return visit found the problem of checks put in place to promote the use of the unit responsibility, and earnestly safeguard the life and property Safety.

Small steam boiler works with its basic principle is the use of small steam boiler: by an automatic control device, to ensure control liquid during operation or high, medium and low probe feedback control electrode opening of the pump, is closed, water supply length, furnace heating time; it is set by the pressure relay with the maximum vapor pressure steam output, the water level falling furnace, when in the low water level (mechanical), water level (electronic), automatic replenishment pump, to the high level, the pump stops replenishment; At the same time, the electric tube furnace heating was continued, a steady stream to produce steam, the upper portion of the top panel or instantly display the steam pressure gauge pointer value, the whole process can be automatic by means of LEDs display. Inspection type widely used in small steam boiler ironing washing industry: dry-cleaning machine, dryer, washing machine, dryer, ironing machine, iron, and other equipments; packaging machinery industry: labeling machines, supporting the use of standard sets of ; bio-chemical industry: supporting the use of a fermentation tank, reactor, sandwich pot, mixer, emulsifier and other equipment; food Machinery industry: tofu machine, steam boxes, cans sterilization, packaging machines, coating equipment, sealing machines, and other equipment supporting the use of; other applicable :( oil industry, automobile) steam cleaning industry (hotels, dormitories, schools, mixing station) hot water supply, (bridges, railways) concrete curing, (leisure club) sauna, hot swap equipment.
