High Quality diesel hot water boiler
Two methods to improve the thermal efficiency of condensing boilers, to master them is to save costs: To put it plainly, improve efficiency condensing boiler heat, that is, for enterprises to save money. But how to do to improve the thermal efficiency condensing boiler it. Fast boiler in the boiler industry with years of experience, concluded: boiler efficiency and network transmission efficiency is the key to the implementation of energy-saving, and in strict accordance with the relevant points to achieve rational use of machinery and equipment to be able to get better and improve the heating effect the operation efficiency of the equipment, while consumers want more reliable to improve the efficiency condensing boiler heating should also follow this principle. 1, to improve the efficiency of the boiler. Rated efficiency condensing boiler efficiency is not a single boiler, but the seasonal efficiency condensing boiler group (group) of. In order to improve the efficiency of the season, to minimize start, stop and standby times each time condensing boiler heating period. This is because each boiler start and stop the purge to go through to consume calories; while in the standby time condensing boiler is quite a large radiator can also cause heat loss. In order to enhance the efficiency of the boiler season group (group), selection is critical design configuration, when the selection needs to consider how the combination boiler has a better ability to regulate and promote the variable load minimum boiler output try to match the minimum load . 2, to improve network transmission efficiency. Factors Affecting network transmission efficiency condensing boiler has three, i.e. thermal insulation, heat losses and leakage caused by hydraulic imbalance, wherein the heat loss due to the horizontal offset of the outer tube and heating the network of vertical imbalance caused very substantial. The proportion of the heat loss of vertical imbalance disorders and horizontal heating chamber outer pipe network condensing boiler thus greatly enhance the efficiency of condensing boiler wants the network transmission efficiency must be improved. Today, the high cost of energy and reduce heat loss offset net condensing boiler tubes is very important. To reduce heat loss pipe network, it should be balanced by hydraulic condensing boiler systems and room temperature control system.
About steam boiler superheater tubes 1 Blasting failure, bursting phenomenon superheater tubes a. Steam discharge sound or explosions near the superheater. B. abnormally decreased steam flow, and the flow is not less than the water flow normally. C. furnace pressure is reduced or made positive, the door severe, see the fire and smoke outwardly steam discharge hole. D. flue gas temperature after superheaters abnormally decreased or increased temperature difference before and after the flue gas superheater. Serious E. Damaged, the boiler steam pressure drop. F. exhaust gas temperature decreased significantly, the chimney flue gas into a gray or white color. g. draft fan load is increased, the current increased. 2, the superheater tubes blasting process a. Superheater tubes minor rupture, may be appropriate to reduce the load, maintain operation in a short time, this time should be closely monitored for leakage, at the same time, rapid start standby boiler. If the monitoring process fault conditions worsen, it should be shutdown as soon as possible. b. When severe rupture superheater tubes must emergency shutdown.

If the gas-fired boiler is seriously short of water, the boiler will be deformed or even collapsed because of the overheating of the hot surface of the boiler, the expansion of the tube will make the expansion tube fall off, the heated surface steel will overheat or overburn, reduce or lose the bearing capacity, and the tube will explode. If handled improperly, damage and so on may lead to more serious consequences. What is the reason why the gas-fired boiler is short of water? The main reasons are as follows: the operator neglects, the monitoring of water level is not strict; after the boiler is discharged, the sewerage valve is not closed, the drain valve is closed, or the drain valve is leaking; the failure of the water supply equipment or the water supply pipe reduces or interrupts the supply of water; The water gauge is blocked by steam and water pipes. Leakage or other causes cause false water level; boiler water wall, convection tube bundle, energy-saving tube or pipe blasting discharge steam. When a water shortage is found, it can be judged by flushing a water gauge called water to determine whether it is slightly short of water or severely dehydrated. The steps for the called water operation are as follows: turn on the water level meter discharge cock; turn off the water level meter steam cock; and close the water meter drainage cock. At this point, if there is water level in the water table, the boiler is dehydrated slightly, otherwise the water shortage is serious. When the gas boiler water supply is slightly insufficient, the water level steam plug can be opened first, the normal operation of the water level gauge can be resumed, the fuel and air supply will be reduced, the combustion will be reduced, and the water can be used. A slow supply of water to the boiler can quickly determine the cause of the water shortage of the boiler. When the boiler water level gradually returns above the low safety level line, increase the fuel and air supply to restore the normal combustion of the boiler.
