oil condensing steam boiler seller

According to fuel (electricity, oil, gas), oil-fired gas boiler can be divided into three kinds: electric condensing steam boiler seller, oil-fired steam boiler and gas-fired steam boiler. According to the structure can be divided into vertical steam boilers, horizontal steam boilers, small and medium-sized steam boilers are mostly single, double-return vertical structure, large-scale steam boilers are mostly three-way horizontal structure. The following is the boiler pressure fire shutdown time more than 6 hours, the boiler main steam valve should be closed after a period of pressing fire, opening the superheater outlet header drain valve, to cool the superheater. If the air pressure rises after the main steam valve is closed, it can be used to lower the pressure of the boiler by feeding the water into the boiler and simultaneously discharging the water. Press. When the boiler resumes operation, it needs to go through the pressure rise and protect step 2. There is still steam pressure in the pot during the shutdown period of the pressure fire, so it is still necessary to pay attention to monitoring and make the boiler keep the allowable water level 3, the boiler with cast iron gas saving gas, after the boiler stops feed water, The gas-saving flue baffle shall be closed, the side-hearth baffle opened or used in the circulating pipeline to stop the water temperature in the gas-saving area exceeding the specified value of 4, the proper discharge shall be carried out during the shut-down of the furnace under pressure fire, and the sediment in the furnace shall be excluded. The operation of circulating water pump should not be stopped immediately after the furnace shut down. The circulating water of network should be kept circulating in the system for a period of time, and the water temperature of boiler outlet should be lowered below 50oC. The operation of circulating water pump can not be stopped until the operation of circulating pump is stopped.

Dry: six gas-fired boiler safety procedures (hot water + steam) stage, the purchase of gas-fired boiler more and more users, in many industries, such as oil exploration, hospital disinfection, chemical production, wine feed, and so on. But many users initial contact with a gas boiler told us how to get started quickly boiler operation is not clear. First, all personnel must be familiar with the operation of the boiler boiler performance and safety knowledge, certificates; this non-job employees Never operate. Duty personnel should strictly follow the regulations, do a good job operating records and shift recording, the security situation should shift equipment and run tests, carried out. When the shift to check the boiler is intact. Second, purchasing, installing, or before the initial operation of the boiler, the boiler and safety accessories must conduct a comprehensive inspection, inspection and determined within the validity period to start. Third, Kai furnace ready to check the gas pressure is within the normal range of values, not too high or too low; check whether normal pump Sheung Shui, if unusual you need to open the purge valve until the Sheung Shui so far. Open the door of each section Water Supply System (including Sheung Shui before and after the festival gates pumps and boilers); check the water level, the water level should be in the normal position, the water level gauge, a water color need to plug in the open position, to prevent false water level, if missing water can be manually Sheung; check valves on the pressure pipe, must be opened, the wind deflector must all flue opening; each knob inspection control cabinet are in their normal position; condensing steam boiler seller check valve is in the normally closed state, heat water boiler circulating pump outlet valve should be turned off; check water softening equipment is operating correctly, soft indicators of compliance with national standards. Fourth, Kai furnace run time 1, steam boilers Open the power to start the burner; check manholes, hand holes around the flange and valve leaks will be tightened, if there is still leakage after tightening occurs, you need to immediately stop maintenance furnace; l when the air pressure 0.05 ~ 0.1MPa, replenishment, sewage, water supply systems and sewage screening test device while flushing water table; when the pressure was raised to 0.1 ~ 0.15MPa, rinsed trap gauge; pressure was raised to 0.3 MPa, the "fire load / small fire" knob to "fire" to strengthen the combustion; 2/3 when the air pressure was raised to the operating pressure, start warming air supply tube, slowly open the main steam valve, to avoid water hammer; out when the drain valve when steam is completely close it; after all drain valve closed, slowly open the main valve to open, and then half a turn; "burner control" knob to "Auto"; level adjustment: adjusting the water level (according to the load manually when to start and stop the pump), low load level should be slightly higher than the normal level, high load level should be slightly lower than the normal level; steam pressure adjustment: adjusting the combustion load in accordance with (manual adjustment fire / small fire) determines combustion conditions The flame color, smoke color determination condition atomisation air quantity and exhaust gas temperature observed concentration chimney, the best change in the combustion temperature to be adjusted according to the combustion. 2, start the circulation pump hot water boiler; startup burner; 15 minutes after start, "" fire load / small fire "spin-bit color button to" fire ";." Burner control "knob to" Auto "five, normal stop 1 furnace, hot water boilers' fire load / small fire "knob to" small fire "; off the burner; close the fuel supply valve; closing dampers; boiler after the temperature dropped to 50 ℃, the pump outlet valve closing cycle ; .2 circulation pump is stopped, the position of the steam boiler "fire load / small fire"; Close combustor; steam pressure drop when the sewage to 0.05-0.1MPA; closing the main steam valve; manual replenishment to the higher level; Close valve; Close supply valve combustion; closed dampers; six off the main power, an emergency shutdown, the steam boiler main steam valve closed; off the main power; 2, boiler water boiler inlet and outlet valve closed; opening the emergency valve and the emergency discharge replenishment valve; off the main power switch; notification superiors.

Fuel condensing steam boiler seller and reciprocating pump works fast boiler company Henan editor that works with you about the structure of the fuel steam boiler fuel steam boiler and reciprocating pump: its compact structure, small size, high efficiency, easy to use, environmental pollution small, medium and large cities in our country is increasingly widely been used. Small fuel gas-fired boilers are generally carried out in the factory oil (gas) volume, water, air volume of commissioning, pressure gauge, safety valve adjustment, and burners, pumps and other auxiliary equipment commissioning, in order to normal operation after the entire boiler factory. A check 1. Check pump and before the filter is normal ignition into the oil boiler, gas furnace check the gas pressure is normal, not too high or too low, the valve opens the supply of oil or gas. 2. The valve on the flue must be fully open (wind deflector or throttle), otherwise the hair wash the affected, causing risk of accidents. 3. Check the control cabinet of each knob, should be in the normal position. For example: oil, gas fuel of choice, should be placed on the fuel combustion; manual / automatic water knob should be placed in the automatic position; fire / flame position small knob, on the small fire position; on the associated combustor knob position. If left in the chamber 4. The product oil or debris should be cleaned. 5. Check the boiler ignition sequence control and fire protection means should be flexible and reliable. Blast doors on the boiler should be flexible, tight. 6. Other inspection items with the same steam boiler (details see this Chapter). All the above work can only be completed after the ignition is started. Second, the fuel gas boiler ignition start (a) auto-ignition process boiler according to claim 1. For process control "Steam Boiler Safety Technology Supervision" predetermined fuel gas boiler to be fitted reliable ignition and flame protection program control means, and for ignition program, the total ventilation time before the ignition and the principles set forth requirements. Fuel gas-fired boiler automatic ignition control procedures are procedures for the operation command center, the heart of the program controller is fully automatic operation, the process control system fully into account all the necessary interlocks to prevent operating errors and accidents caused by equipment failure, It represents good security. Core within the process control system is a controller are basically three: (1) a mechanical process controller; (2) electronic program controller; (3) real-time control microcomputer program controller. But whatever the controller uses, roughly five main steps procedure: automatic furnace purging process, the program auto-ignition, flame protection program, program safety interlock protection, the combustion load adjustment procedure. There leak gas boiler control program. Belonging to the reciprocating pump displacement pump, it is to rely on reciprocation of the piston or plunger of the pump cylinder, the pump cylinder working volume cyclically expanded and reduced to suction fluid. Reciprocating pumps generally consists of two basic components, to achieve an end pressure energy is converted into mechanical energy, and part of the liquid fed directly, or said hydraulic cylinder end portions; and the other end is a power transmission part, said power end.
