how to calculate hot water boiler thermal efficiency

Boiler safety is what is involved and what the boiler island? Boiler, it will be security risks which, is the need to pay attention to the workers? And, What is the boiler island? In addition, oil-fired boiler, which is typically what oil? These three questions are about the boiler, so the following to answer it, so we have to learn content to deepen their knowledge and understanding of the extent of the boiler. 1. boiler safety problems, mainly what? Boiler may or security risks exist, in general, there are mainly the following, are as follows: (1) boilers, certainly there will be high pressure steam or hot water, so to try to stay away to avoid burns . Further, combustion equipment and boiler hot ash, is a high temperature, therefore, is to be away, they avoid being scalded or burned. (2) in the boiler room, it is possible that dust pollution is serious, and therefore should pay attention to, in order to avoid damage to human health. Also, pay attention to the terms of noise, if there is noise pollution, so as not to make the hearing impaired.

What preparations before a gas steam boiler operation needs to check various instruments, meters are normal. B, circulating water system and the boiler feed water system, without exception, each of the valve opening degree reaches a predetermined state. c, check gas pressure not less than 10000Pa, gas pipeline leak. d, reset operation before combustion process controller. E, soft water tank check, confirm adequate water to open the valve. f, check the boiler water supply is normal. g, demineralized water inspection system is working properly. h, check the dosing device is working properly and adequate dosing barrels of liquid. i, if there are other abnormalities within the boiler inspection. j, check the boiler water level, pressure, temperature, ignition and flame detection of the four protection means, the fuel feed line pumps and valves be carefully checked debugging. k, after the above examination was normal, by air through the main power switch to turn the key switch, without passing inspection and testing of the boiler, the ignition operation is prohibited.

Hefei Limin Pharmaceutical Co., Ltd. Nanjing Military Region, formerly the backbone of pharmaceutical companies, the main drug is slowly swallow rather teabag, relying on advanced R & D platform to carry out contract manufacturing, OEM OEM and other business cooperation. China's environmental protection development trend began to take shape, many environmental policies have been put forward for a positive response to the national environmental policy, Limin Pharmaceutical decided to introduce a gas station steam boilers. After an investigation of the boiler market, Limin Pharmaceutical fast boiler is strong comprehensive strength and wealth of experience working for many years in the pharmaceutical industry to attract, party fast according to the actual needs of customers for its recommendation of one of Taiwan 4 tons of steam condensate gas-fired steam boiler (WNS4-1.25-YQ).

Chemical water supply system of Boiler

There are many calcium and magnesium salts in tap water, and the water quality is hard. If it is not softened, it will be directly added to the boiler, which will cause precipitation of calcium carbonate, magnesium carbonate and magnesium hydroxide, which will deposit on the inner wall of the water pipe/water bladder. Thermal efficiency, long-term past, boiler thermal efficiency will be lost. Chemical water supply system of Boiler focused on removal or chemical modification of substances potentially damaging to the boiler.
