Steam boiler in Vietnam sugar mill

industrial steam boiler play an important role in vietnam sugar mil. these industrial steam boiler include, biomass boiler, oil gas boiler, coal fired boiler, among these steam boilers, biomass(bagasse) fired boiler are widely using in sugar mill. hence, we call it sugar mill boiler.

Energy in Vietnam sugar mill

The remaining fibrous solids, called bagasse, are burned for fuel in the mill’s steam boilers. These sugar mill steam boilers produce high-pressure steam, which is passed through a turbine to generate electrical energy (cogeneration).
The exhaust steam from the turbine is passed through the multiple effect evaporator station and used to heat vacuum pans in the crystallization stage as well as for other heating purposes in the sugar mill.
Bagasse makes a sugar mill more than energy self-sufficient; surplus bagasse goes in animal feed, in paper manufacture, or to generate electricity for sale.

Sugar mill boiler in Vietnam

For many years, sugar mill steam boiler have burned bagasse, the fibrous byproduct of the processing of sugarcane, using special boilers that produce the steam needed to help break down the sugar cane.
As the cost of powering this equipment by burning fossil fuels has steadily risen, the use of biofuel cogeneration as a source of power production has become more prevalent. Many sugar mills have updated their bagasse-fired boilers and linked them to generators that produce electricity used to power the mill’s operations and to be sold to the local power grid.
3d组选347开奖前后关系 Optimizing combustion efficiency and achieving cleaner burning throughout the process will generate more electricity and steam, and reduce harmful emissions. These results can be achieved if the equipment used in the cogeneration process is frequently tested using a portable emissions analyzer.

Combustion Efficiency & Safety

3d组选347开奖前后关系measuring the levels of o2 (oxygen), co (carbon monoxide), and cxhy (hydrocarbons) being emitted from biomass(bagasse) fired boilers will inform the mill’s operators if their equipment is burning the biomass cleanly and efficiently. achieving higher efficiency will allow them to minimizing the amount of auxiliary fossil fuel being used to help power the system.

Environmental Emissions

monitoring the co2, so2, and nox emissions from the bagasse boiler system is necessary to ensure compliance with current environmental regulations and to minimize environmental and health hazards. emissions measurements should also be taken before and after the flue gas cleaning system to ensure the efficient elimination of any corrosive components present in the system.

Water tube steam boiler in Singapore

water tube steam boiler in singapore has a large demand. most of singapore industry buy oil gas water tube steam boiler, some buy biomass fired steam boiler. the opposite steam boilers structure are firetube steam boilers.today, we mainly talking about water tube steam boiler design in singapore market.

Water-tube steam boilers design type in Singapore market:

Description of water tube steam boilers including operation, types and benefits; also, a brief synopsis on how they are applied to combined heat and power generation.
Water-tube steam boiler design
Water-tube steam boilers differ from shell type steam boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.

Water tube steam boiler design

Water-tube steam boilers are used in power station applications that require:
A high steam output (up to 500 kg/s).
High pressure steam (up to 160 bar).
Superheated steam (up to 550°C).
However, water-tube steam boilers are also manufactured in sizes to compete with shell steam boilers.

Water tube steam boiler design

3d组选347开奖前后关系water tube steam boiler design

Small water-tube steam boilers may be manufactured and assembled into a single unit, just like packaged shell steam boilers, whereas large units are usually manufactured in sections for assembly on site.Many water-tube steam boilers operate on the principle of natural water circulation (also known as ‘thermosiphoning’). This is a subject that is worth covering before looking at the different types of water-tube steam boilers that are available. Below Figure helps to explain this principle:
Cooler feedwater is introduced into the steam drum behind a baffle where, because the density of the cold water is greater, it descends in the ‘downcomer’ towards the lower or ‘mud’ drum, displacing the warmer water up into the front tubes.

Natural water circulation in a water-tube steam boiler

Continued heating creates steam bubbles in the front tubes, which are naturally separated from the hot water in the steam drum, and are taken off.
3d组选347开奖前后关系 However, when the pressure in the water-tube steam boiler is increased, the difference between the densities of the water and saturated steam falls, consequently less circulation occurs. To keep the same level of steam output at higher design pressures, the distance between the lower drum and the steam drum must be increased, or some means of forced circulation must be introduced.

Alternative water-tube steam boiler layouts

The following layouts work on the same principles as other water-tube boilers, and are available with capacities from 5 000 kg/h to 180 000 kg/h.
Longitudinal drum boiler
The longitudinal drum steam boiler was the original type of water-tube steam boiler that operated on the thermo-siphon principle (see Figure Longitudinal drum steam boiler below).

3d组选347开奖前后关系cooler feedwater is fed into a drum, which is placed longitudinally above the heat source. the cooler water falls down a rear circulation header into several inclined heated tubes. as the water temperature increases as it passes up through the inclined tubes, it boils and its density decreases, therefore circulating hot water and steam up the inclined tubes into the front circulation header which feeds back to the drum. in the drum, the steam bubbles separate from the water and the steam can be taken off.

typical capacities for longitudinal drum boilers range from 2 250 kg/h to 36 000 kg/h.
