oil fired normal pressure hot water boiler

Gas steam boiler how gas consumption is calculated: gas consumption gas steam boiler how to calculate: there are a lot of users do not know how to calculate the gas consumption of gas steam boiler steam boiler gas before you buy, there are a lot of phone users consulted, this this problem has plagued some users, it decided to write it again this morning article on "how gas consumption gas steam boiler computing", following on from me explain to you about the principles of operation of the gas boiler gas consumption formulas and gas boiler. 1. First, we first look at the gas steam boiler operating principle: the pressure of the fuel through the gas line is controlled by the flow valve through the ignition burner Automatic combustion air, the heat emitted by the heating surface of the boiler sufficiently absorbed (three return) flue gas (carbon dioxide and water) into the atmosphere through the chimney. 2. Gas-fired steam boiler fuel consumption cost analysis (we have a 4-ton gas-fired boiler, for example) fuel light oil and gas projects Rated evaporation 4t / h2t / h thermal efficiency of 92% to 92% fuel heating value 8500Kal boiler / Nm310300Kal / Kg fuel consumption amount 300Nm3 / h24Kg / h auxiliary mechanical and electrical consumption 11KW · H11KW · H fuel Price yuan / Nm3 yuan / Kg fuel costs per hour yuan per hour RMB auxiliary mechanical and electrical consumption costs the first year cost of fuel (million, according to 350 days / annualized) in the auxiliary equipment costs (million yuan, according to 350 days / year basis) of the total cost (million, according to 350 days / year basis) (Note: at 12 hours per day)

Gas boiler safe operating procedures: gas-fired boilers this kitchen I believe we are not unfamiliar fishes it. But this thing is not so easy, and sometimes improper operation causing very serious consequences, so the gas boiler rules is very important. That in the end this is how the specific operation of it, if you want to know, quickly told us with a look. 1. All personnel must be familiar with the operation of the boiler performance and safety knowledge of the boiler operating certificates. This post is strictly prohibited non-operating personnel. Duty should be strictly in accordance with the operating records and do a good job shift recording, the security situation and the device should shift change operation tests, carried out. When the shift to check the boiler is intact. 2. Boilers and safety accessories should be inspected, and in the period. 3. Kai blast furnace gas furnace ready ① Check if the gas pressure is normal, not too high or too low, open the door of oil and gas supply section; ② Check whether the pump Sheung Shui, or opening the purge valve, until the Sheung Shui so far. Open the Water Supply System for each section of the door (front door section Sheung including pumps and boilers); ③ check level gauge, the water level should be in the normal position, the water level gauge, a water level required color plug in the open position, the water level to prevent false, if water can be manually Sheung; ④ check valves on the pressure pipe, must be opened, the wind deflector must all flue opening; each knob ⑤ checks the control cabinet are in their normal position; ⑥ steam boiler check valve should be in the closed state fired normal pressure hot water boiler circulating pump outlet valve should be turned off; ⑦ checking water softening equipment is operating properly, a variety of indicators to create a soft water meets national standards. Open the power ⑴; ⑵ startup burner; ⑶ purge valve on the drum, is completely out of steam, the off; ⑷ inspection hole into the boiler, and the hand hole flange valves, the leak was found to be fastened, tight as the solid leakage maintenance shutdown; ⑸ pressure rise when 0.05 ~ 0.1MPA, replenishment, sewage, water supply systems and sewage screening test device while flushing water table; ⑹ when the pressure was raised to 0.1 ~ 0.15MPA, flushing pressure gauge trap; ⑺ when the pressure was raised to 0.3MPA, "fire load / small fire" knob to "fire" to strengthen the combustion; ⑻ when the pressure was raised to 2/3 of the operating pressure, start warming air supply tube, slowly open the main steam valve, to avoid water hammer; ⑼ drain valve is completely closed out of steam; ⑽ after all the drain valve closed, slowly open the main valve to open, and then half a turn; ⑾ "burner control" knob to " Auto "; ⑿ level adjustment: adjusting the water level (to manually start and stop the pump) according to a load, low load level should be slightly higher than the normal level, high load level should be slightly lower than the normal level; ⒀ steam pressure adjustment: adjusted according to a load combustion (manual adjustment Fire / small fire) ⒁ combustion state determination, determines the amount of fuel atomization air ⒂ observation condition exhaust gas temperature, smoke, temperature control is generally between 220--250 ℃ The flame color, smoke color, while observing the chimney exhaust gas temperature , concentration, adjusted to the optimum combustion state. ⑴ Open the power; ⑵ start the circulation pump; ⑶ slow circulation pump outlet valve; ⑷ startup burner; ⑸15 min "" Load fire / small fire "bit color button is turned to" fire "" ⑹ "burner control" knob spin to "automatic." 5A normal shutdown: hot water boiler ① "fire load / small fire" knob to "small fire"; ② off the burner; ③ close the fuel supply valve; ④ ⑤ closing dampers boiler after the temperature dropped to 50 ℃ , the circulation pump outlet valve closed. ⑥ stop circulation pump

"Professional life, work fine", which is the party adhere to the core values ​​of fast. Whether the overall boiler or details of the site, both parties soon to be subtle, not ignore every aspect. Single-minded attitude is a solid foundation for the development of innovation. Not forgetting beginning of the heart, was always square. Fang fast since its inception, adhere to the development road of clean fuel boiler, to respond positively to our policy, efforts to promote road boiler industry to environmental protection direction. Facing the future, parties will continue to fast innovation and creativity on the development of the first, and unswervingly take the road of clean and green, to provide users with a more secure and reliable boiler cleaning solutions.

Phenomenon and deal with local boiler furnace boiler and leaking drain There are many methods of treatment, there are many, for example, took the furnace leaks and frequent leaks, the approach is not the same, gave the following an analysis leaking furnace approach: 1, the inner wall of leakage: Patching, water provision and pipe down pipe leak on the exchange. 2, the outer wall of leakage: paste film, or contact the manufacturer for 1 year. 3, easy to burn out grate reasons: the high volatile coal is recommended for coal. 4, after the boiler water overflow, add cold water or hot water first find the cause overflow, if it is a cold pan, fill the tank overflow tank with water may be small, do not add water up. 5, the approach to maintenance, divided into the following two methods: ① chemical cleaning: chemical cleaning agent is added to the dispersion in the system is discharged rust, dirt, oil cleaning, reduction of cleaning metal surfaces; ② routine maintenance: Add GR- 943C inhibitors, to avoid rusting of metal, to prevent the crystalline precipitate calcium and magnesium ions. 6, the water level is higher than the house inside the house if the valve is still low ① automatic purge valve, the water level must be higher than the house of the bleed valve. ② house valves automatically vent valve or a direct-to-air pipe. ③ If a house straight tube deflated, of course, will lower the water level inside the house than the discharge pipe. Boiler its small size, low power consumption, a typical feature is suitable for home use, boiler leakage is a very serious problem, it will affect the results, we want to do before using the equipment all ready fault prone, precautionary measures in the first place.
