The flame tube is arranged centrally, offset slightly downwards. The hot gas flues of the second and the third pass are arranged symmetrically above. The high pressure steam boiler generates 1 to 30 ton/hr. The operating pressure extends from 6 to 20 barg (28 barg, 30 barg on request). With the associated system technology, the boiler utilizes fuel particularly efficiently.
Effect on Environmental Operation of the three-pass boiler is environmentally responsible with clean combustion throughout the entire output range. A constant temperature where the flame is created supports stable flame formation and reduces NOx emissions.

Easy Maintenance
Steam boiler is designed with longitudinal double drums and "D" type chamber structure. The body is fixed on the basement by middle and both end flexible supports and make the boiler expand horizontally sideways. Around the furnace is membrane water cooling tube wall. Furnace and tube bank are totally separated by the membrane water tube cooling wall at the left side of the furnace. The back part of bundle is sparse shift structure, front part is aligned structure.
Smoke from furnace outlet enters re-burning chamber, convection tube bank area and then from left front part enters spiral fine coil economizer and finally is discharged to atmosphere through chimney.
Technical advantages:
• Safety
Boiler body uses the forced circulation in the high temperature area to make sure all heating areas can be cooled down and avoid vaporization;
The explosion door and flame detector are equipped for safe and reliable operation.
Comb plates are used between both sides of boiler and tube bundle to avoid leakage of condensate and gas caused by using refractory concrete as sealing material. Air proof test is done before delivery in the factory to guarantee any gas leakage problem.
• Convenience
Manholes are placed on the front and back side of drums and inspection doors on back side of boiler easy to open for inspection and clean inner and outer parts.

“RAY” oil & gas combination burners of the BGEC series are industrial duo-block burners. They combine the oil and gas burner. They are modular, based on the building block principle and consist of the burner, an air reservoir, the separately installed blower and the fuel feed line and control.

The series is suitable for parallel or separate combustion of all technical fuel gases as well as gas and all mineral heating oils and combustible liquid waste materials. The control unit used as standard ensures that oil/gas is used sparingly and makes it easier to operate and maintain the burner. All essential functions such as fuel and air supply or flame monitoring are controlled with precision. Due to the modular burner structure and the resulting flexibility, they can be used for a large number of special applications. Individual project planning, a short planning phase and high system availability are guaranteed. The use of the RAY oil/gas combination burner allows a free choice of fuel for economic or operational reasons.

ADVANTAGES
  • Burners for combined operation of oil and gas for alternative or combination firing
  • Use for liquid fuel and any kind of gas
  • Change-over and fuel selection automatically, also by remote control

Economizers

Economizers and air heaters perform a key function in providing high overall thermal efficiency of the boiler by recovering the low level, that is, low temperature heat from the flue gas before it is exhausted to the atmosphere. For every 20 °C that the flue gas is cooled by the economizer or air heater, the overall boiler efficiency increases by approximately 1%. The economizers recover the energy by heating the boiler feed water while the air heaters preheat the combustion air. Coal combustion is enhanced and coal ignition becomes stable when the air is heated before being introduced into the furnace. Economizers and air heaters require a greater heat transfer surface per unit of heat recovered than water-cooled walls, super heaters and repeaters; this is mainly due to the relatively small temperature difference between the flue gas and the feed water or the combustion air. Both the economizer and the air heater are positioned near the end of the convection pass.

Air paeheater

Air Preheater is an important Boiler auxiliary which primarily preheats the combustion air for rapid and efficient combustion in the furnace. The air heater recovers the waste heat from the outgoing flue gas of a Boiler and transfers the same to the combustion air. In a utility Boiler the flue gas leaves the economizer at a temperature of around 350°C. As every 55°C drop in flue gas temperature improves the Boiler efficiency by about 2.5%, having an air heater in the downstream of economizer the Boiler efficiency is considerably improved. Further the air heater may also be used for heating the air to dry the coal in the pulverizing plant.

Boiler room (steam boiler)

1. EQUIPMENT / SAFETY & CONTROL
• Description
The steam boiler control system includes an additional monitoring electrode for supervision of water level. This type-tested electronic system allows automatic operation without steady supervision according TRD standard (𝑇𝑒𝑐ℎ𝑛𝑖𝑠𝑐ℎ𝑒 𝑅𝑒𝑔𝑒𝑙𝑛 𝑓𝑢 ̈𝑟 𝐷𝑎𝑚𝑝𝑓𝑘𝑒𝑠𝑠𝑒𝑙) or according to Thai regulation
2. FEED WATER PUMP STATION UNIT
• Description
Pump module for pumping boiler feed water. All components included in the standard delivery are perfectly matched ready to connect and pre-assembled on a space saving mounting bracket. Feed water pump can be used in liquid temperature range: -20 oC up to 120 oC
3. FEED WATER TANK & DEAERATOR UNIT
• Description
Feed water tanks are heated storage tanks that do not have aspecific de-aerating section and operate at atmospheric pressure. In addition to being a feed water reservoir, these tanks also act as condensate receivers, cold-water makeup locations and as a point for chemical injection. Given the multitude of functions this vessel can have, proper design and operation of the feed water tank is critical to ensure the boiler sees fully treated feed water consistently. A properly designed feed water tank will help reduce thermal shock and decrease oxygen scavenger usage. Avoiding the four most common design issues with feed water tanks can help reduce problems with your boiler feed water system.
4. STACK UNIT
• Description
While rain guards are often necessary in our climate to protect certain equipment from a in entering a stack, there are acceptable and unacceptable design. Rain caps installed on stacks must allow for unobstructed, vertical flow of the exhaust.
5. STEAM HEADER UNIT IN BOILER ROOM
• Description
The steam header, water distributor and water collector are the main auxiliary equipment of the boiler. They are used to distribute the steam or hot water generated during the operation of the boiler to various pipelines. The steam header, water distributor and water collector are a pressure-bearing equipment, which belongs to pressure vessel. Its pressure-bearing capacity and capacity should correspond to the supporting boiler. The main pressure components of the steam header, water distributor and water are: head, shell material, etc. The steam header can be used in various steam boilers. Water distributor and water collector can be used in all kinds of hot water boilers. Steam header is a steam tank for use in the process and steam to warm water in the feed tank.
6. BLOW DOWN UNIT
• Description
The periodic/continuous blow down expansion container is connected with the periodic/continuous. blow down outlet of the boiler. It is used to decompress and expand the periodic/continuous blow down of the boiler, so that the blow down water in the periodic/continuous blow down container can be separated into secondary steam and waste hot water. The waste hot water is discharged after expansion, pressure reduction and heat exchange in the expanded container, and the secondary steam is drawn out by a special pipe. Periodic/Continuous sewage discharge can be adjusted automatically with the change of boiler feed water load to maintain a relatively stable sewage discharge rate. The blow down tank is designed to accept all for steam boiler.
