szs two drum water tube boiler Water tube boilers have many advantages . The cross section of the water tube boiler tube is smaller than that outside the tube, so the steam flow rate is greatly increased, and the steam generated on the heated surface is immediately washed away, which increases the heat absorption rate of the water.
two drum water tube boiler advantages | Textile Industry . Two Drum Bent Tube Boiler The working principle of cross drum boiler is same as longitudinal drum boiler. 1) The feed water What is a two drum water tube boiler | LinkedIn. Two drum water tube boilers include three types, which is chain grate type, D type, circulating fluidized bed type.
From the superheater, about one-third (30%) of the superheated steam passes to the turbine and the remaining two-thirds (70%) is used to evaporate the feed water in the evaporating drum. The Loeffler boiler has the capability to generate 100 tons/hour of steam at a temperature of 500° C and a pressure of 140 bar. Advantages of Loeffler Boiler
Operating Principle: A water tube boiler is typically formed of four parts, a lower feed water drum – sometimes known as a mud drum – an upper steam drum with water surface from which the steam is evolved, water tubes connecting the two drums together and a super heater / economiser section (depending on the quality of steam required).
Nineteenth Century saw the first use of boiler drums and defined water circulation. Higher-pressure requirements that appeared in the late Nineteenth Century led industry to move away from cast and wrought iron to steel. Development continued with the elimination of brick settings, the introduction of bent tubes and multi-drum units, the

Two drum water tube boiler. The D type boiler can burning oil and gas fuel with high efficiency, which has the advantages of reliable operation, automatic control, clean and environmental protection. Two drum traveling grate water tube boiler can burn both coal and biomass fuel. With chain grate combustion style, the fuel could be burnt fully.
Hence water tube boilers can quickly generate steam at the required pressure than the fire tube boiler. 2. Steam at higher pressures can be produced: The water tube boilers do not contain any tubes inside the boiler drum. Hence the water tube boilers can withstand high pressures for the same wall thickness and the thermal stresses. Therefore water tube boilers can develop higher pressures than the fire tube boilers. 3.

Water-tube boiler. The heated water then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam will reenter the furnace through a superheater to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure.
The Loeffler boiler is an internally fired furnace with forced circulation, high pressure and water tube boiler. In Loeffler boiler, 75% of superheated steam is used to evaporate the water within the evaporator drum and the remaining 25% of the steam from the superheater is utilised by the turbine.
