condensing hot water boiler oil fired boiler gas

Coal-fired boilers, fuel shots are fired, coal in the combustion chamber after the combustion heat release, the heating medium water or other organic heat (e.g., heat transfer oil, etc.) heated to a temperature (or pressure) of the thermal power plant. Coal is our energy use accounted for first, with a mature mining, transportation and sales channels, and the price is relatively low; but it also has many defects, low efficiency, resource utilization imbalance, burning emit large amounts of carbon dioxide and other harmful gases and dust, the larger impact on the environment pollution and high environmental costs.

Three matters needing attention in daily maintenance of condensing boiler

The invention and use of boilers have a long history, and the use of condensing boilers, to a certain extent, makes full use of the heat of flue gas and water vapor itself, which is a more environmentally friendly way. And all-in-one condensing boiler price is fair. However, in the process of operation, maintenance is needed to ensure the stability of the operation. The following three aspects should be paid attention to in the daily maintenance of the condensing boiler.

1, attention should be paid to the maintenance of boilers as required to a large extent in order to check and detect the existence of problems in condensing boilers in order to be able to solve or prevent problems in a timely manner, and this will also avoid further expansion of the problems. It protects the furnace from further damage and should be careful not to add antifreeze in the water. All premixed aluminum condensing boiler manufacturers introduce that if the newly installed condensing boiler system should be thoroughly flushed, the remaining oil paper or metal debris and other impurities in the boiler should be removed.

2, pay attention to the fact that this step of installing filters is indispensable and can largely prevent the boiler from being damaged. Some preparations should be made before the condensing boiler is opened for official operation. Water circulation, for example, should take up to two hours so that impurities can be removed first. Condensing boiler manufacturers also remind after the end of operation, should be timely to open the safety valve, further removal of impurities inside.

3. Pay attention to cleaning work before installation. Before installation, special additives are also needed to clean all pipes. And condensing boiler manufacturers emphasize that cleaning agents must be neutral and absolutely not to have any acidity or alkalinity in order to avoid corrosion to the equipment. In short, it should be done according to the requirements of the manufacturer. Because the materials of ordinary condensing boilers are silicon-aluminum alloy, so they are very sensitive to alkaline substances, so the ph value of hot water in the boiler should never be controlled within the prescribed range of mixed additives must be prescribed by the manufacturer. You can't use other types at will.

Gas introduced gas steam boiler steam boiler stop sign Profile: natural gas steam boiler is a steam boiler gas, natural gas steam boiler with natural gas as fuel, the combustion in the furnace heat put out by heating the pot water, and allowed to vaporized into steam energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace temperature is increased and produce steam under pressure. Since the boiling point of water increases with increased pressure, the pot is sealed, the expansion of water vapor generated inside the pressure limited thermodynamic formed, strictly speaking, the steam boiler is heated in water at constant pressure saturated steam drum regasification water formed, is widely used as an energy source. Protection device: (1) protect the boiler water a boiler water level gauge plate supporting one to two, should always be compared with each other, inconsistent findings indicate that shall be corrected immediately. Class water level should be flushed, to determine their true level. While the water level comes electrode rod can accurately capture level signal to an alarm or a pump control. (2) steam pressure protection pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switches, other control lines or automatic control chain protection. Using pressure controllers and electrical contacts, the vapor pressure can overpressure alarm; single adjustable pressure controller or dual fire burning fire the actual operating pressure. Safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. (3) having a burner flame protection flame protection inlet means, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged combustible residual gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. (4) self-locking power failure protection case, the boiler shutdown immediately burst self-locking power interruption, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition. Editing boiler ignition procedures: 1. Check operation and (or) shift recording. 2, inspection, examination boiler, external. 3, check the main safety accessories. Safety valve, water gauge, pressure gauge, to be tight, reliable and sensitive. 4, check the water treatment equipment. 5, inspection equipment and soda water supply system pipe. Adjust the valves as required to start. 6. Check the oil supply equipment. After the above inspection qualified, you can start the boiler. Note: The boiler is a high-temperature, high-pressure thermal equipment, is one of special equipment, widely used in government agencies, public companies and all walks of life, it is dangerous and special equipment. Event of an accident involving public safety, it will cause huge losses to the state and people's lives and property. For public safety, people's lives and property safety, according to the State Council, "Regulations on Safety Supervision of Special Equipment", the boiler should use full attention the following matters: 1, should be accompanied by safety technical specifications of the factory boiler design documents, product quality certification, safety and the use and maintenance instructions, supervision and inspection certificate (safety supervision, inspection and performance certificate). 2, boiler installation, maintenance, alteration. Engaged in the installation of the boiler, maintenance, renovation of the unit shall obtain special equipment installation and maintenance certificates issued by the Provincial Quality and Technical Supervision, before engaging in the boiler installation, maintenance, alteration. Construction unit before construction will be prepared for installation, maintenance, alteration in writing inform the special equipment safety supervision and management department of the municipality or district, and will start informing sent to the local county level Quality and Technical Supervision for the record, told immediately after construction. 3, inspection of boiler installation, maintenance, transformation. After construction, the construction unit To State Quality and Technical Supervision of Special Equipment Inspection and hydrostatic testing of the boiler installation supervisory inspection declaration. After passing by the State Quality and Technical Supervision, State Special Equipment Inspection, County of Quality and Technical Supervision involved in overall acceptance. 4, registration boiler. After the boiler inspection, the use of units must be in accordance with the "special equipment registration and use of management rules", fill "boiler (census) Registration Form", the State Quality and Technical Supervision to register and obtain a "registration certificate to use special equipment safety . " 5, operation of the boiler. Boiler operation must be performed by trained and qualified to obtain "special equipment operator certificate" certified personnel to operate, must strictly abide by the rules and eight systems, six record. 6, check the boiler. Periodic inspection of boiler once a year, not be used without safety periodic inspection of boilers. Safety accessories safety valve of the boiler regular inspection once a year, pressure gauge biannually verified, may not be used without the periodic inspection of the safety accessories. 7, non-pressure boilers will be installed for the boiler pressure. Do not use water level gauge, safety valve, pressure gauge three safety accessories insufficiency boiler.
