straw hot water boiler for printing plant sitong gas
What type steam boiler type steam boiler of what we can from different angles on the boiler category:? 1, according to the working fluid can be divided into natural circulation boiler, forced circulation boilers, DC boiler. 2, according to the boiler flue gas flow tube, a shell boiler (fire tube boiler), combined fire tube boiler. 3, according to the installation package boilers, boiler assembly, bulk boilers. 4, according to the boiler drum placed vertical, horizontal boiler. 5, according to the purpose of life boilers, industrial boilers, utility boilers, boiler travel. 6. The medium steam boilers, straw hot water boiler for printing plant sitongs, soft drinks dual boiler, boiler organic heat carrier. 7. The water circulation natural circulation, forced circulation and once-through boiler, combined cycle. 8, the pressing force pressure boilers, low boilers, medium pressure, high pressure boiler, high pressure boiler. 9. The internal combustion boiler combustion, external combustion boilers. 10, according to the fuel fired boilers, oil-fired boiler, gas-fired boiler, pulverized coal boiler, waste heat boiler, electric heating boilers, biomass boilers. There are many types of steam boilers, the key is that you need which, because of the different classifications, so in different places, will be used to different steam boiler, so as to better ensure use. Working principle of a steam boiler heating device (burner) to release heat, radiation heat transfer is first absorbed by the water wall, the Wall Boiling water, a large amount of steam into the drum for water separation (excluding DC furnace), the separated saturated steam entering the superheater, and continues to absorb the top horizontal flue furnace by radiation, convection, heat of the flue gas flue of the tail, and the superheated steam to reach the required operating temperature. Power generation boilers are generally provided with a reheater, it is used to heat the steam through the high pressure cylinders acting reheater go out of the reheat steam, the low pressure cylinder to continue to generate power.
Impact of straw hot water boiler for printing plant sitong energy consumption indicators of a number of things because China has been working to coal to gas roaring blaze of glory, the choice of hot water boiler, a very large reduction of dust contamination, together with nitric oxide and other gases affect health the smoke get suppressed. Energy consumption index is an important measure of labeled water boiler, behind a number of things we look at the impact of energy consumption indicators due to hot water boiler. After study of the persons concerned, and hot water boilers consume more important comes from two places: the ideal ratio is not sufficient combustion air flue gas emissions as well as waste heat. Reduce flue gas emissions can be equipped with a waste heat chimney latent heat recovery equipment in the tail of hot water boiler, or choose a more leading boiler system FGR. The combustion air is not fully over the inappropriate induction ratio: usually hot water boiler combustion machine ejector, formed air-fuel ratio can not be automatically scheduled. A majority of the hot water boiler using a mechanical blower burner, causing the air-fuel ratio is not ideal because there is something behind several aspects: air-fuel ratio is not ideal for the more important can be divided into two conditions: when too much air, there will be a large number of excessive cold air is heated, resulting in improving the energy consumption of hot water boilers, hot water boiler energy consumption index dropped; when there is insufficient air, to produce incomplete combustion conditions, hot water boiler energy consumption indicators declined.
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; steam boiler 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 straw hot water boiler for printing plant sitong; 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.
In the square, accompanied by Mr.?Mahbubul fast group of professional boiler foreign trade, the group visited two intelligent production workshop, national R & D center and a full laboratory conditions has been the recognition and appreciation Mr.?Mahbubul. Not only is our company's hardware conditions attracted Mr.?Mahbubul, results in the software also lets Mr.?Mahbubul Gee praised. Mr. Mahbubul it comes to the process of communicating with us, the boiler can not guarantee the purchase of multinational concerns about the safe operation of the boiler; and our unique remote monitoring cloud service system is just perfect solution to this problem.
