The power plant in Bulgaria consists of 11 1800kw 2000kw 2400kw best conventional boilers sized 160 and 220 t/h, fired with natural gas and coal. In order to meet the changing emission regulations and to reduce the fuel cost the customer was interested in replacement of 2 existing 220 t/h gas-fired boilers with a new CFB boiler fired with petcoke and Ukrainian semi -anthracite. Gas boilers no 7 and 8 were demolished, this space was used for a new CFB boiler plant .

Gas-fired steam 1800kw 2000kw 2400kw best conventional boiler safe operation Tidbits gas steam boiler safe operation Tips 1. The operator should be familiar with the structure and principles of the furnace and the production of basic requirements for thermal equipment, and constantly sum up experience in practice, control coal thickness, so that the full combustion reduce chimney smoke, protect the equipment in a safe, efficient operation. 2. The new oil furnace or restart long home, gas steam shall dehydration stage heating requirements. 3. export oil temperature should be set below 280 ℃, when the oil temperature exceeds 200 ℃, should pay more attention to temperature, oil temperature should slow down, only non-oil change and over-temperature operation. 4. close contact with production, timely and slow down the oil temperature, while meeting production requirements, taking oil lower, will help extend the life of gas and steam energy savings. The normal oil level: the lower tank oil level is low, high-high oil groove. This ensures that the emergency shutdown when cold oil replacement system and prevents air from entering the pipe. When the high slot in a low oil level should start to replenish gas steam injection pump. 6. The circulation pump is allowed outage in the operation of the burner, when the pump is failure or power outage, Fan stop, depending on oil temperature and take appropriate emergency measures: rapid opening valve 7, the cold head tank oil up through the furnace coils to the low tank. 8. Coal and wet coal hearth fire or discharge out of the furnace, non-water washed pouring furnace. These measures should be completed within 3 to 5 minutes, to prevent the high oil temperature coke deposits other accidents. 9. normal shutdown, the oil temperature should be reduced to below 100 ℃, stop the pump before. 10. When the outlet pressure differential below the set value, the induced draft fan should outage. Then there is a fault system, feedback should be immediately removed or, if necessary, should pressure fire outage. 11. fireman should stick to their posts, do a good job operating records and shift work, and regular inspection and maintenance equipment.

Fast 1800kw 2000kw 2400kw best conventional boiler is a very trustworthy business, whether it is the beginning of cooperation or boiler put into operation, such as a party soon have maintained cooperative attitude, patience, careful. To ensure long-term stability of the latter part of the boiler operation, fast boiler technician fireman's gave us a free people to do the training, precautions and reduce the accident rate method full guidance boiler operation. --customer feedback

Gas 1800kw 2000kw 2400kw best conventional boiler heat loss through the combustion of fuel gas boiler, will release some heat, which will supply part of the user, some will be recycled and part is inadvertently wasted. So these are wasted heat lost through the ways in which it (1) heat losses:? Flue gas exhaust gas boiler part of the heat into the atmosphere, causing the boiler heat losses, it is each boiler term heat loss Dazhong biggest one. The main factors influencing the heat loss is higher exhaust gas temperature and the amount of smoke exhaust gas temperature, the greater the amount of smoke, the greater the heat loss. Low exhaust gas temperature depends mainly on the number and operating conditions of the heating surface; the amount depends on how much leakage exhaust case and the furnace excess air, flue. (2) heat loss incomplete combustion gas: a part of the unburned combustible gas is discharged with the flue gas to heat loss caused by heat in the flue gas. The main factors affecting the incomplete combustion gas heat loss is the excess air and furnace structure. Excess air coefficient is too small, uneven air is mixed with fuel, easy to generate carbon monoxide and other combustible gases; excess air coefficient is too large, the furnace temperature is lowered, the combustible gas is not easy ignition and combustion. Furnace volume is too small, combustible gases in the furnace too late to enter the combustion flue gases caused by incomplete combustion heat loss. (3) heat loss: the furnace heat loss, frameworks, pipes, door opening caused by heat dissipation to the surroundings. Size depends on the heat loss factors of the size of the surface area of ​​the furnace gas steam boiler, heat insulating properties and thickness, the outside air temperature and the flow velocity. Electric heating reactor common external damage: an electrically heated reactor despite external corrosion has a high etching resistance against acid and alkali resistance, but our electrical heating by the heating apparatus is a kettle layer and an outer tire iron constituted. Such a medium is iron acids and bases are not corrosion-resistant. If we would have the production process if the reactor cover or screwed pipe joints without seal failure or leak acid tire iron reactor apparatus for electrically heating the outer corrosion. Corrosion support member 2. The reactor was heated electrically heated reactor during installation, support or other support member may be mounted directly on the floor, due to the long manufacturing operations on the floor may be deposited with corrosive media, so that for support our reactor electrically heated apparatus corrosion, resulting in the supporting force of each of the support produces a change resulting in a change in stress in the damage produced during heating layer. 3. The electrically heated reactor stress spout in the electrically heated reactor, when the steel of the pipe and the pipe joint, since the thermal deformation and the reaction was heated electrically heated autoclave vessel or duct stressed cold might damage the pipe.
