At present several common boiler energy-saving technologies: usually for boiler manufacturers, it means that you are saving boiler to maximize the interests of customers, providing customers with unlimited fuel savings, the electricity consumption, water consumption and so on. But the wide range of energy-saving, does not refer to an aspect of optimization can save energy boilers, here's a look now common boiler energy-saving technologies: 1 furnace arch. Industrial boiler furnace arch is very important. Arch role is to cause the furnace hearth and the organization of the mixed gas and the radiation hot flue gas flow, ignition and combustion of the fuel in a timely manner. At present, the actual amount of industrial chinese fired steam boiler with its rated load often do not match, the use of coal varies widely, but often with the design coal are quite different, so in actual use, often as necessary for the furnace arch modified to meet the needs of coals. Heteroaryl coal used by the inferior design coal, the boiler furnace exit gas temperature occurs is low (about 700 degrees), lower than 200 degrees design.

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.

How to ensure the normal operation of the gas chinese fired steam boiler steam boiler gas used in the process in order to ensure the proper and safe use, in the design of on improving the allocation of system protection, common protection system has five steam boilers are: water protection , pressure protection, temperature protection, flame protection, power protection self-locking, followed boiler Co., Ltd. for your details each steam boiler protection system. Gas steam boiler water level to protect the five common protection systems: steam boiler is equipped with two sets of pumps, operation and use. Boiler water level gauge plate supporting one to two, should always be compared with each other, findings indicate inconsistency shall be corrected immediately. Class water level should be flushed, to determine their true level. And also has balanced water level electrode cartridge point can accurately collect to alarm level signal or to control the pump. Common pressure protection systems protect the five gas steam boiler: steam pressure protection: When the boiler pressure exceeds the rated value, the need for chain protection: is shutdown, the system stops the combustion; fire mouth can also be varied, single-stage or two-stage combustion You can also adjust the amount of oil, so the buck, to ensure the safe operation of the boiler. Steam boilers and pressure protection as the water level, the use of multiple protection: safety valve pressure controller. Temperature protection gas steam boiler five common protection systems: temperature protection is an important procedure in the safe operation of the boiler, is particularly important for the regulation and protection of the boiler temperature steam; at the same time to regulate protective role in over-temperature hot water boilers. Prevent explosion of the furnace, the fuel (gas) boiler flame protection means must be provided, is a function of combustion (including ignition, combustion or misfires when halfway off, typically within five seconds re-ignition furnace in the monitoring, within 1 second running off into the oil (gas) solenoid valve, and turns on and audible alarm signal, when the blower continues to operate, the residual gas was purged of combustible furnace, after 20 to 30 seconds purge, automatically cut off the blower and various auxiliary power boiler stop running.) by the flame monitoring and control device component.
