Sitong Boiler products

The structure of SZS series gas fired water tube boiler is arranged as drum longitudinal type “D” shape, it’s quickly assembled boiler with water tubes, has the characteristics of high steam quality, sufficient output, and high thermal efficiency (97%), etc. The structure of furnace water cooling wall and convection gas pass is membrane wall, have good sealability, and effectively reduce refractory brick quantity and maintenance workload. The layout of economizer at boiler tail could effectively reduces exhaust gas temperature and improve boiler thermal efficiency. This series gas fired water tube boiler is delivered as whole when leave factory, convenient for transportation, and has a short install period.

Sitong coal fired thermal oil boiler is a safe and energy saving boiler with working characteristics of low pressure (0.8 MPa) and high temperature (350℃). The combustion equipment could be chain grate or fixed grate, The heat carrier is heat conduction oil, the circulating pump force heat transfer medium circulating in liquid phrase, and transfer heat to heat user equipment, then return to the heating furnace for reheating. Because of working in liquid state, the coal fired thermal oil boiler is safe and reliable.

DZL series coal fired stoker boiler is single drum, the combustion equipment is chain grate stoker. Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and screw fire tube in the drum are convection heating area. This coal fired stoker boiler uses the upper drum, water wall tube and head are in symmetrical arrangement mode. The drum is welded assembly by cylinder and front back tube plate. This furnace structure in reasonable arrangement and high efficiency. This stoker boiler adopts several environmental protect measures (bag dust collector, double towers desulfurization, etc.) to meet the national emission requirement. This series coal fired stoker boiler uses the new scientific achievement, such as arch tube plate, screw fire tube to solve the problem of tube plate flaw, water wall tube explosion, low efficiency, insufficient output, poor adaptability of coal, improve the heat transfer.

Biomass pellet fired water tube steam boiler is horizontal type double drums water tube boiler with high steam quality, the combustion equipment is chain grate. Sitong boiler takes several breakthroughs on boiler design, such as membrane water cooling wall, low thermal inertia design, and water cooling combustion chamber. This biomass pellet steam boiler adopts fast assembly or packaged assembly structure, boiler with steam capacity lower than 4t/h is fast assembly water tube structure, boiler with steam capacity between 6~25t/h is consisted of upper part (boiler heated part) and lower part (combustion equipment). This series boiler has reached the international advanced level on technology and performance, it has the advantages of compact structure, high steam quality, sufficient output, operate convenient and environmental protection.

Solid fuel fired chain grate boiler is single drum water tube and fire tube boiler, combustion equipment is chain grate. Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and screw fire tube in the drum are convection heating area. This boiler uses the upper drum, water wall tube and head are in symmetrical arrangement mode. The drum is welded assembly by cylinder and front back tube plate. This furnace structure is in reasonable arrangement and high efficiency, also, it adopts unique double secondary air design to improve the high combustion efficiency. The solid fuel fired steam boiler uses the new scientific achievement, such as arch tube plate, screw fire tube to solve the problem of tube plate flaw, water wall tube explosion, low efficiency, insufficient output, poor adaptability of coal, improve the heat transfer.

Sitong Boiler have developed a fixed grate, moving grate, chain grate and chamber combustion four combustion modes, and three body structure: horizontal pipe, single longitudinal, vertical longitudinal.

Sitong YY(Q)W series gas fired thermic oil boiler is a safe and energy saving boiler with working characteristics of low pressure (1.0 MPa) and high temperature (330℃). It is patent products of Sitong Boiler, the patent number is ZL 2014 2 0508472.3. The heat carrier is heat conduction oil, the circulating pump force heat transfer medium circulating in liquid phrase, and transfer heat to heat user equipment, then return to the heating furnace for reheating.

The thermal efficiency of industrial electric boiler reaches as high as 99%, and there is no NOx released to the air. The electric boiler with steam capacity lower than 1ton is designed as vertical structure, and higher than 1 ton is designed as horizontal type to offer sufficient steam output. The electrical control cabinet is separate from boiler body, which will not affect the boiler’s working life because of the aging of the electrical elements. The electric steam boiler adopts high quality electrical heated tube, work for about 20000 hours. It uses stainless steel electric heating tubes has high compression strength, the working life is 5~10 times longer than the common tubes. The industrial electric steam boiler is ideal for heating, textile plant, rice mill, garment factory, utility or power plant, hospital, hotel, food & beverage, diaries, schools, chemical industry and more applications.

Generally, low pressure boiler refers to that boiler pressure is lower than 1.5 MPa (15 bar). The temperature in a low pressure boiler will not rise above 120℃.Sitong Boiler is professional on low pressure boiler, and the representative low pressure boiler is thermal oil boiler, which is working under the pressure of 0.8Mpa, while it can get a relative higher temperature (320℃) than the ordinary boiler.

Sitong boiler offer oil burner, gas burner and oil gas dual fuel burner for industrial oil gas boilers, based on customers’ specific requirement. The brands of the burner are Italy, Baltur, and Rellio, have the advantages of high quality, combustion sufficiently, low NOx emission, and low gas consumption when atomization.
