The reason you need to know the boiler energy consumption (reheat steam temperature) reheat steam temperature problems 1. Circumstances reheat temperature rises 1.1 Move boiler furnace flame center, furnace outlet temperature increases (see main economic indicators No. 5 boiler exhaust gas temperature). 1.2 coal increased too fast. 1.3 Excess air amount is increased. 1.4 pulverizing system start-stop. 1.5 Automatic control of the reheater desuperheating water improper adjustment. 1.6 reheater sootblowing time poor choice. 1.7 feed water temperature is low. 1.8 the high pressure turbine exhaust temperature is high. Next to the 1.9 high leakage, high reheater inlet temperature. Hot and cold extraction section greater then 1.10. 1.11 boiler heating surface design is unreasonable, over-temperature reheater tube wall, forced cooling operation. 2. Reheat the following partial flame temperature is lowered center 2.1: burner tilt deviation, hem; burner is switched from the upper to the lower layer, the lower layer or to an excessive amount of the powder; volatile coal fraction is increased, the pulverized coal thinning, water reduction. 2.2 reheater heating surface fouling, slagging, fouling the interior. 2.3 Save reheat the heated drain valve. 2.4 automatic adjustment inappropriate, excessive reheater desuperheating water. 2.5 feedwater temperature. 2.6 economizer and water wall sootblowing time poor choice. 2.7 reduce the amount of coal too fast. 2.8 # 1, # 2 high pressure heater is disabled, increasing the reheated steam flow.

In the process of Hainan with the pharmaceutical companies, the other either for my company's product or service we are very satisfied with our company's reputation and expressed trust. --customer feedback
You know how the boiler works? Boiler parameters is a main boiler performance indicators, including the boiler capacity, steam pressure, steam temperature, water temperature and the like. Boiler capacity available rated maximum continuous evaporation or evaporation is represented. Rated evaporation under a predetermined outlet pressure, temperature and efficiency, the amount of steam per unit time of continuous production. Maximum continuous evaporation under a predetermined outlet pressure, temperature, per unit time the maximum continuous amount of steam produced. Steam pressure and temperature parameters including steam boiler manufacturers rankings, generally refers to a superheater, superheated steam pressure and temperature at the outlet of the reheater and superheater if no reheater, saturated steam pressure and temperature at the outlet of the boiler refers. Refers to a water temperature of the economizer inlet temperature, inlet temperature refers drum without economizer. Boilers can be categorized in different ways. Boiler use can be divided industrial boilers, utility boilers, marine boilers and boiler locomotive; by the boiler outlet pressure can be divided into low, medium, high pressure, high pressure, sub-critical pressure, the supercritical pressure boiler; boiler and by water flue gas flow path can be divided into the fire tube boilers, fire tube boilers and water-tube boilers, fire tube boilers and wherein the fire tube boiler and collectively shell boiler; press cycle can be divided into natural circulation boiler, auxiliary boiler cycle (i.e., forced-circulation boilers), and the combined circulation boiler once-through boiler; by combustion, the boiler chamber into the burner, and boiling Stoker furnace. Water vapor system, feedwater heated to a temperature in the heater, the water supply pipe into the economizer, after further heating into the drum, along with the mixing pot of water down to the water wall downcomer inlet header. Radiative heat absorbing soda water formed by the mixture in the riser in the drum reaches the waterwall tubes, the water from the steam separator means, steam separation. The separated saturated steam from the superheater to the upper stream drum, continue to become superheated steam endothermic certain temperature (most of the current 300MW, 600MW unit main steam temperature is about 540 ℃), and then sent to the turbine. In terms of combustion and flue gas system, the air blower into the air preheater is heated to a certain temperature. It is ground to certain fineness in the mill coal, a portion of the hot air from the air preheater carried into the furnace through a burner. Discharging pulverized coal burner and combustion air mixture is mixed with the rest of the hot air in the furnace and release large amount of heat. The hot flue gas flowing through the furnace sequence after combustion, Slag bundle, the superheater, economizer and air preheater, and then through the dust removal device, wherein the fly ash is removed, and finally sent to the chimney by the induced draft fan to the atmosphere.
Compared with the coal fired boiler, natural gas fired boiler for sale in ZG Boiler has high efficiency, low combustion and less pollution, and it is convenient to install, environmentally friendly as well as energy-saving. Natural gas fired boiler can be divides into two types according to its output, one is gas fired hot water boiler, which is usually applied in daily life; and the other is the gas fired steam boiler manufacturers rankings, which is mainly applied in industrial production. Both of them can take city gas, biogas, natural gas and other gas as its fuels.
